Zealth Audio: Employing Homeless Veterans

If you’re like me, little things sometimes frustrate you. Maybe the kids left the cap off the soda again and it went flat. Or your spouse put a small scratch in the bumper of your sports car. Possibly the cat left you a present in a remote corner of a spare bedroom….

Then you learn about someone like Kevin Nelson and it puts everything in perspective. Nelson (about whom I’ve written previously), is the founder and owner of Zealth Audio, a small speaker company based in San Diego. He’s an eternal optimist who puts his money where his mouth is—literally—and does business a little differently.

zealth audioNelson is very open about the rough times he’s experienced in his life. After returning from his military service in the U.S. Navy, he spent years in homelessness in San Diego. Despite the hardship of living in shelters and on the street, it was during this time that his dream of designing and selling his own high-fidelity speakers took shape.

Fast forward to 2015. Nelson is now happily occupied designing new and affordable speaker models and with the effort of growing his fledgling company.

If that was the end of the story, it would be inspirational enough. But Nelson believes in giving back. Plus, he knows, first hand, the plight of homeless vets who have given so much for their country, only to face hardship and challenges after returning home. Hardship and challenges that, too often, lead to substance abuse, poor health, and even an early grave.

Thus, he hatched a plan. Nelson’s company, which hand-builds each set of speakers in a wide variety of beautiful wood finishes to the specifications of his customers, employs homeless veterans. For each set of speakers ordered, Zealth Audio temporarily hires one or two homeless vets at his small shop in Southern California.

During an interview, Nelson was frank with me about his inspiration for hiring vets to build his unique speakers. “I got the idea while on the streets, watching my fellow veterans just fall apart. Sometimes I would find them dead; it happened three times to me. So I made up my mind, right then, that I would not quit ’til I could do my part and help some veterans,” he said.

“I know how it is, so I can talk with them very easily. I can help them with resources they don’t know about. San Diego is a beautiful place, but it’s money hungry, so it really doesn’t have good places for the homeless. That stuff you see on TV about shelters is staged…they are a living hell,” he told me.

When asked about how he selects homeless vets to help him, Nelson responded, “The veterans I help have to be in a program with the VA [U.S. Department of Veteran’s Affairs] or in a shelter trying to get life back on track. I help those that are getting something done. I know several still on the river, where I stayed when I was homeless. I will bring them in as long as they are sober—ya still gotta be tough.”

Nelson said he is frustrated by how both veterans and the homeless are treated in the United States. He’s critical of what he perceives to be the hypocrisy of many who claim to help the homeless or support veterans. “Don’t tell me how much you support them. Show me,” he said from his shop.

Nelson’s company wasn’t around when I was shopping for the speakers that populate my two home theaters. If it were, I would have seriously considered purchasing from Zealth simply to avoid padding the bonus of a CEO who probably wouldn’t have been employing military veterans down on their luck to build me audiophile-quality speakers.

The next time you’re feeling sorry for yourself, remember Kevin Nelson and Zealth Audio. Remember the homeless vets who are being given another lease on life by one of their own who, by the miracle of his own determination and hard work, has managed to escape a life on the street.

That man is now giving back, not only by selling killer speakers that satisfy audiophiles like me, but—more important—by helping others to rehabilitate themselves.

Zealth Audio: Great American Speakers

3d1When I was doing research for one of my latest books, Home Theater for the Internet Age, I knew I couldn’t get lazy with the Speakers chapter. So I put a lot of time into the topic. In the process, I discovered some neat, small speaker companies.

Most of the experts I truly respect in the areas of hi-fi and home theater agree: You should put the bulk of your budget into speakers (for a wide variety of reasons that I won’t go into here).

One of the more unique and affable companies I encountered during my research was Zealth Audio. Based in San Diego, Zealth isn’t your father’s speaker. To learn more, enjoy the following excerpt from my book.

Zealth Audio

If you’re one of those people who likes to talk about supporting the little guy, but ends up plunking down your hard-earned on speakers from a big international corporation, you might want to consider your options. Independent manufacturers, some of which are as small as one full-time craftsman working with one or two part-time assistants, are increasingly common. Fortunately, some of these little guys can also save you significant money while putting a hand-crafted speaker in your living room that’s actually attractive and sounds great.

One such option is Zealth Audio, a small operation in San Diego that hand-builds four models of multi-directional floor standing loudspeakers, all of which are designed to enhance surround sound—although they work well in stereo applications as well. Like Mirage, Pinnacle, and Axiom, Zealth stands out in the sometimes copycat world of direct-firing loudspeakers by offering a unique design that caters to the realities of modern surround sound.

What truly differentiates the speaker-design brainchild of company founder and sole full-time employee Kevin Nelson is the fact that it’s designed to work in a two-channel stereo sound system with as few as one—yes, that’s right, one—speaker. Zealth employs a patented Cross-Fire Imaging Technology, which comprises both front-firing and 45-degree up-firing Picture-002drivers. Zealth also sells a three-way speaker that adds a side-firing subwoofer.

Nelson claims that all of his configurations “enhance your existing surround sound-enabled investment and bring home theater sounds to breathtaking life,” referring to the experience as “multi-dimensional sound immersion.” Nelson is so confident in the immersive quality of his speakers, in fact, that he says you can replace a conventional five-speaker system with only two of his models. When I asked him if one could also avoid the expense of a subwoofer by going with his top-of-the-line side-firing Gold Series model, he said yes.

If you’re as curious about Zealth as me, check out the company’s entry-level ZAL-22 ($450 a pair), the midgrade ZAL-36T ($890 a pair), or the big daddy ZAL-DLX Gold Series, a 36-inch tall model featuring the aforementioned side-firing 10-inch subwoofer ($1,450 a pair). Nelson is also introducing a new faux leather finish ZAL36 Slimline model that will be priced at $980 a pair.

All Zealth speakers are made-to-order, hand-built from American materials, and available in more than a dozen beautiful wood finishes (a nice alternative to the trendy high-gloss piano finishes that are all the rave—and one advantage of Zealth’s small-scale fulfillment system). The company produces muscular models that, according to veteran audiophile reviewer Steve Guttenberg, sound as good as they look.

Check out Zealth. You’ll not only be supporting the little guy, but also getting a killer set of very affordable speakers. The ZAL-36T is what I plan to use in a new two-channel system dedicated to music.

[According to Molly Stillman at rAVe Publications, who interviewed Nelson for her blog in April 2014,Speaking with Kevin was truly a pleasure and an honor. He was extremely humble, very honest, funny, witty, and clearly very smart. I think the industry could use a few more Kevin Nelsons.” You can read Ms. Stillman’s blog post regarding Zealth Audio here.]

Common Confusion in Home Theater: Part 8

3d1In the previous blog post, we discussed how the room in which you place your home theater (or two-channel audio system) can greatly affect the quality of the sound produced. In this post, let’s explore room correction and room dynamics (the size and shape of the room and the nature of the stuff in it).

  • Part 1: Volume and zero dB, updating firmware, disadvantages of Blu-ray
  • Part 2: Speaker resistance and analog vs. digital amps in AV receivers
  • Part 3: PCM vs. bitstream and Blu-ray player upscaling/upconversion
  • Part 4: THX certification, DLNA network access, and distortion and THD
  • Part 5: HDMI (including cable length and controversial expensive cables)
  • Part 6: Closed-back vs. open-back around-ear headphones
  • Part 7: Understanding your room and room dynamics
  • Part 9: Ethernet, separates, and broadband internet routers

Room Correction

Many AV receiver models, especially those manufactured within the past five to eight years, feature something called room correction (also called auto-calibration or automatic EQ). In a nutshell, room correction, as its name implies, makes small adjustments to the speaker outputs of the receiver based on your particular room layout in an effort to improve your sound—with a focus on surround sound and the combined effect of all of your speakers.

The task of room correction involves a small microphone that plugs into your AV receiver. The receiver produces a series of test tones from each individual speaker that are “heard” by the calibration microphone, which provides feedback to the receiver. The receiver uses this information in two ways. First, it adjusts the relative loudness of your speakers so they’re all producing sound at the same level (based on the position of the microphone during testing). Second, it attempts to determine how your specific room acoustics are affecting and harming the quality of the output of your speakers and applies equalization (EQ) to try to improve the situation.

Don’t downplay the importance of good room correction. “I didn’t realize how much better [music] could sound until I finally took the 30 minutes to run the [room correction] program. Wowza, what an experience! The surround channels seemed to come to life, and the bass response throughout the room was much more consistent and pleasing to the ears,” said David Vaughn in a receiver review for Sound & Vision magazine.

If your receiver doesn’t feature built-in room correction (many don’t, especially entry-level models), you can use a supplemental tune-up disc (a good example is Sound & Vision Home Theater Tune-Up, available for about $15 from resellers like Amazon). Most products of this type offer a comprehensive set of tests and tools to adjust and enhance both your audio and video, including speaker placement, sound levels, and other audio settings. Another, albeit more expensive, option is hiring a certified technician to calibrate your home theater (installers often offer this service).

Speaker Position & Room Dynamics

As you learned in the A Word About Your Room section of the Components chapter, it’s important to realize that the room in which your speakers reside has a dramatic effect on the quality of the sound produced by them. This includes the volume, clarity, and dynamic range perceived by you and your listeners. Rooms that provide too much sound wave reflection, or, conversely, too much sound absorption, will color the audio produced by any speaker. The shape of the room also heavily influences the path traveled by sound waves before they reach your ears, significantly influencing your perception of the sound.

The position of speakers is also critical and applies to both two-channel systems as well as 5.1 and larger surround configurations. Not only is the position of speakers relative to each other significant, but also their locations relative to the room and walls. Is your home theater environment fully enclosed? Partially open? Mostly open? What is the nature of the surfaces of the walls? The ceiling? Is the floor highly reflective ceramic tile, or a deep-pile sound-absorbing carpet? How dense is the furniture and decor in the room? These are all important considerations that go beyond the inherent quality of the speakers themselves.

Understanding Home Theater Speakers: Part 2

3d1Speakers are arguably the most important part of any home theater setup. They’re certainly where one should invest the bulk of one’s money. You’ll keep good speakers a lot longer than any other home theater gear, especially AV receivers, disc players, and streaming media boxes.

Center Channel

The center channel, as you’ve already learned, is dedicated to TV and movie dialog (it’s nice to hear the sound coming from where a character’s mouth appears) and enhancing the overall immersive quality of music emanating from the speakers facing you. As mentioned, it’s highly advised that your center is from the same series as your front mains. More powerful center channels feature more drivers. Thus, a basic config might be a single midrange or full-range driver, while a more sophisticated example would feature a couple of woofers, one or more midrange drivers, a tweeter, and maybe even ports.

It should be noted that most high-resolution surround sound music formats, such as SACD, and DVD-Audio, all give music publishers the ability to record a center channel as part of a song or album. (See the Disc-Based Music chapter for more information regarding these high-resolution music formats.) Center channel speakers range in cost from under $100 to several thousand.

Subwoofer

As you’ve already learned, a subwoofer is simply a speaker dedicated to the lowest audio frequencies, which you can literally feel in addition to hear. If you really want to shake the house or wake the neighbors, a large, powerful sub can do it. Barry White should have owned a sub company.

A sub is unique in that, unlike your other speakers, it’s a powered unit (300 to 800 watts is common). Don’t dismiss the capabilities of a high-quality 10, 12, or even 15-inch subwoofer. For movies especially, it will become one of your favorite speakers (and something you’ll want to turn down when the kids are asleep).

Omnidirectional

The subwoofer is also unusual among other speakers in that it’s mostly omnidirectional, meaning where it resides in the room and where it’s pointed (the direction in which it fires) are much less important than with your other speakers. This is nice for tucking it discretely behind a sofa or under an end table. Some models, like the uniquely slim $1,400 Paradigm MilleniaSub and the $2,000 REL Habitat1, are specifically designed for narrow spaces, such as under a sofa.

Most subwoofers feature a digital amp. While models with Class A/B analog amps are available, they’re less common. Incorporating a digital amp allows a model to be smaller, consume less energy, and perform with greater efficiency. Just to confuse things, there are also hybrid varieties that employ both analog and digital circuitry at a variety of prices and quality levels. Like other speakers, some subs feature relief ports, a nice addition because ported subs can produce greater output. Subs that aren’t ported are called sealed (just like headphones). The PB series from SVS is a good example, featuring models with between one and three ports each, priced from $500 to $2,000.

Driver Configs & Second Helpings

Like regular floor standing and surround speakers, subwoofers can feature one or more drivers that fire in a variety of directions. The most common configuration is side firing (like my 10-inch, 500-watt, single-driver sealed B&W ASW700) or down firing (like the 10-inch, 150-watt REL T-5). Klipsch’s best sub, part of its Palladium Series, features two 12” drivers powered by 1000 watts that are side firing and 90 degrees separated (this sub is arguably overkill for most rooms). The majority of subs feature a single side-firing driver that’s between 10 and 15 inches in diameter and commonly powered by 500 watts.

As you’ve learned, some home theater hobbyists add a second sub to their home theater, creating a more balanced low frequency experience with even greater impact. However, in dual-sub environments, placement is critical; typically, you don’t simply stack them on top of each other. The debate between one big sub or a couple of smaller units will never cease in the audiophile world. In the end, it’s determined by your room and budget.

Understanding Home Theater Speakers: Part 1

3d1I’m continually reminded of how those of us who consider ourselves home theater enthusiasts often forget that many of those around us don’t get into it like we do. Recently, I had a couple of non-enthusiasts remind me that they didn’t understand woofers and Blu-ray players. Which is great, because that’s the business I’m in: Teaching regular middle class people about confusing consumer tech.

Speakers are arguably the most important part of any home theater setup. They’re certainly where one should invest the bulk of one’s money. You’ll keep good speakers a lot longer than any other home theater gear, especially AV receivers, disc players, and streaming media boxes.

The following is an excerpt from my Kindle book Home Theater for the Internet Age. In the next blog post, we’ll discuss the all-important center channel (which carries the bulk of the spoken dialog of the actors in a TV show or movie) and the booming low-frequency subwoofer—thus rounding out the basic speaker positions in a six speaker, 5.1 home theater surround sound configuration.

Dynamic Loudspeakers & Drivers

The most common type of speaker, from a technical perspective, is the dynamic loudspeaker. The term “speaker” can mean a few things, but is generally a reference to a single unit, in the form of a box-like enclosure, that contains one or more drivers. Drivers feature a cone (visible from the front of the speaker) made from a variety of materials—cheap ones being paperboard and nice ones being Kevlar or metal (typically aluminum or titanium). Behind the cone resides a mechanism involving a coil (sometimes called a voice coil) and a magnet. This coil, magnet, and cone-based driver is responsible for the extreme weight of good speakers (generally speaking, higher-quality speakers are heavier because they feature larger, more powerful magnets in their drivers).

Woofers & Tweeters

Dynamic loudspeakers feature the familiar and onomatopoeic woofer and tweeter combination, where the woofer carries the low and maybe some mid-range frequencies and the tweeter projects the high-end sounds. The most basic loudspeakers feature a single driver, whereas more sophisticated models include multiple woofers and midrange drivers, a powerful tweeter, and maybe even one or two acoustic resonance ports. Technically, with the exception of resonance ports, these are all “drivers,” or coil/magnet/cone devices capable of emitting sound. Thus, a speaker with a woofer, midrange, and tweeter has three drivers.

Form Factors

Each type of speaker that composes a full surround system plays a particular role in creating an immersive audio environment and dealing with particular types of sounds that are projected from specific areas of your room. These different roles manifest themselves in distinctly unique form factors, from the tall floor standing models flanking your display panel to the lone center channel that carries mostly movie dialog.

Floor Standing

Floor standing speakers, also called “mains” or “towers,” are typically the largest in your home theater and play a prominent role in delivering the impact of action movies and music. They carry the lion’s share of the sound in a surround mix, and are sometimes the only source of sound if you’re playing a stereo music CD (and don’t apply a special DSP field to turn it into artificial, or matrixed, surround).

Floor standing speakers are the bridge between the old world of “stereo systems” and the new world of surround sound. You’ll inevitably want to use your home theater to listen to music. If you’re really into music and, for example, you’re going to spend 50-80% of your time listening to it, and only the minority watching TV or movies, it makes sense to invest most of your speaker budget on the best towers possible. This may involve even going a bit downmarket for your rear speakers (but it’s highly advised that your three front speakers are from the same series). As you’ve learned, some people skip the subwoofer entirely so they can afford the best possible floor standing models while pursuing their dream stereo system.

Bookshelf / Surround

What are sometimes called “bookshelf” speakers (in a two-channel stereo configuration) are often labeled “surrounds” in a home theater. They’re basically junior models of the large floor standing models. They’re not necessarily lower quality; they simply feature less power and fewer drivers than their floor standing big brothers.

There are two options for the rear speakers in your surround system: Standard front-firing bookshelf speakers or dedicated multi-directional models. Dedicated surrounds create a more immersive effect. The design you choose depends on your personal tastes and room dynamics. Both good and bad examples of each approach are readily available. It’s more important to get a quality speaker with a wide frequency response and low distortion than to labor over the differences between these two designs.

You already know that you should purchase your surround speakers from the same series as your mains. Speakers from different series, and especially different manufacturers, can feature tonal discrepancies (different timbre) that will degrade the quality of your audio. A mismatched set also won’t look as nice sitting in your living room. That said, it’s sometimes better to have good speakers from different series than lousy units from the same line. Utilizing speakers from different series or manufacturers isn’t a cardinal sin and won’t necessarily produce bad sound; it’s simply not optimal.

If your home theater resides in a relatively small room or you’re on a tight budget, one option is to use robust bookshelf speakers for your mains also. While this may decrease your music listening pleasure (particularly at higher volumes), it will still sound good for movies if you purchase nice models, especially those that hit relatively low frequencies. Down the road, when you have the cash for proper floor standing mains, you can demote those front bookshelf speakers to center surrounds in a 7.1 system. (Often, the home theater of your dreams is not a matter of having a pile of cash to blow at one time, but rather being patient, planning intelligently, and building your system over years.)

Home Theater: Surround Sound Basics

3d1Today’s blog post continues our look at home theater, following yesterday’s Home Theater Basics. Below you’ll find an excerpt from my new book, Home Theater for the Internet Age, regarding surround sound. Most people understand that surround sound involves a speaker arrangement in your living room or dedicated home theater that “surrounds” you (duh).

This is a pretty radical departure from the common arrangement to which most of us (unless you’re a millennial) are acclimated: Sound that emanates from in front of us—typically from the display device, the TV, itself. The old method of projecting sound from the display was rife with deficiencies. First, the speakers built into even the best, most expensive, TVs suck. Period. There’s no physical room in a relatively thin panel for real speakers.

Modern home theater has introduced a more complex audio arrangement in which dedicated, much higher quality, speakers are positioned to the sides or even behind viewers. Because the sound is being projected from locations other than the display panel and is generated by real speakers, surround sound is the cornerstone of true home theater. However, because there’s so many types of surround sound arrangements, the topic can quickly become confusing for non-enthusiasts or those new to home entertainment.

Today we’ll address surround sound configurations. These are the physical layouts of speakers and the logical dispersion of audio channels from TV shows and movies. What’s 5.1? What do the “5” and the “1” mean? Why does your buddy at the office lust for 9.1? Read on to eliminate your confusion.

Also check out Home Theater: More Surround Sound and Home Theater: Surround Sound Formats.

Surround Sound Configurations

As you’ve learned, there are several different physical configuration standards for surround sound, ranging from five to twelve speakers (and sometimes more). Arrangement shorthand is indicated by a decimal number, such as 5.1. This indicates five surround speakers and a single subwoofer. The number of subwoofers is always indicated to the right of the decimal (5.x). A 5.1 AV receiver is capable of outputting to a maximum of five speakers and a single subwoofer. A high-end 9.2 receiver, on the other hand, is capable of driving nine speakers and two subwoofers. If a friend says she has a 6.1 system, you know she has seven speakers total and that one of them is a sub. While uncommon, it’s possible that someone might have, for example, a 5.3 system, in which they have a basic surround complement and three subs (yes, some videophiles install multiple subwoofers).

You’ve already learned the basic role of a subwoofer, or “sub.” In surround sound, the sub carries the LFE, or Low Frequency Effects, channel. Most movies and some TV programming feature an LFE channel (identified as such on your AV receiver). Capable of emitting ultra-low frequencies below 80 Hz, subwoofers are as much about what you feel as what you hear. This low frequency speaker plays in the zone where sound goes from audible to tactile. If a movie indicates that it features “x.1 audio,” it means there’s a dedicated LFE channel (regardless of whether you have a subwoofer to bring this channel to wall-shaking life).

Typically, surround configurations range from 2.0 to 11.2. The most common config is 5.1 (although 2.1, while not providing any surround effect, is also very common). Try not to get surround envy. 9.1 and 11.1 systems are very rare and, arguably, complete overkill for the average consumer. Also, relatively few films and basically no TV shows are encoded in a standard above 7.1 (although this is rapidly changing). Thus, even if you had a fancy 9.1 system, a small percentage of the content you consumed would support it, making it a very expensive upgrade. (I have a 5.1 system and rarely lust for the two additional rear speakers of a 7.1 configuration. If I was going to upgrade, based on the size and layout of my living room, I’d probably never go beyond a 6.1 layout.)

It should be noted that all of these surround configurations are backward compatible, meaning that a 7.1 or 9.1 soundtrack will play just fine on a 5.1 system (or even a 2.0 system) or via headphones. That’s part of the magic of Dolby and DTS and modern home theater receivers.

2.1 & 5.1

Because this book defines home theater as having a minimum of five speakers, a 2.1 setup involving three speakers (two mains and a sub, with no rears) isn’t covered in detail. This type of configuration includes soundbars (see the Soundbars & Theater-in-a-Box section of the Speakers chapter for more info). While this setup doesn’t provide “surround” sound, it can—with even basic equipment—greatly enhance your time with music, TV, movies, and games. It will perform remarkably better than your TV speakers (those built into even high-end display panels are basically an afterthought, producing really crappy sound).

5.1 systems involve two mains (typically floor standing models, but sometimes bookshelf units), a center channel, two rear surrounds (called the left side surround and right side surround), and a subwoofer. Sometimes consumers opt to skip the subwoofer to save money (or because they underestimate the effect it will have during Blu-ray movies). Most videophiles consider 5.1 the entry-level setup for true home theater. If your AV receiver supports 7.1 speaker outputs, a 5.1 system gives you room to grow; simply purchase two additional speakers and you’re in business. While your front three speakers should always be from the same series to ensure timbre-matching, it’s less important for your rear and side surrounds to be from the same line (but still preferable for a variety of reasons).

6.1 & 7.1

Moving up the ladder, more complex surround configurations are 6.1 and 7.1. These involve one or two additional rear speakers, positioned directly behind the viewers, called the left back surround and right back surround—not to be confused with the left side surround and right side surround positions in a 5.1 or larger system. Should you go the extra mile and install one or two extra speakers between your existing surround positions? If you’re a big movie buff and your room is large enough to justify it, maybe. You won’t have trouble finding movies to fill this many speakers; most films today deliver a minimum of 7.1 surround audio channels (even some high-res music albums feature a 6.1 surround mix).

Remember that your AV receiver must support the number of speakers to which you want to expand. If you have a receiver capable of only 5.1, you’ll not only have to purchase one or two additional back surround speakers, but also a new receiver (as you’ve learned, this isn’t cheap, especially if the unit produces clean, robust amplification).

9.1 & 11.1

The average home theater owner probably shouldn’t pursue a 9.1 or larger surround sound configuration. However, it’s important to know one’s options. For very large rooms—or hyper-hobbyists who are pursuing the most realistically surrounding audio environment possible—one of the layouts involving more speakers than a 7.1 system might be appropriate. Of course, it will cost you. You’ll either have to increase your speaker budget or downgrade the quality of your candidates. Those additional speakers—especially if they match your other models—don’t come cheap.

A 9.1 system adds front height channels to the mix (the left height and right height positions), giving—as the name indicates—a taller and seemingly wider front soundstage than a 5.1 or 7.1 system can deliver. 9.1 is the first standard to address the expansion of the front soundstage (whereas 7.1 adds audio imaging to the rear area). Not only would you need to purchase additional speakers to satisfy the needs of a 9.1 system, but you’ll probably need to upgrade your AV receiver to handle the additional amps and terminals. And it hardly makes sense to upgrade without pursuing a few more watts or maybe going Class D. Cha ching.

An 11.1 system goes even further by adding left wide and right wide speakers, positioned at roughly 60 degrees from a forward-facing viewing position (to the left and right of the front height speakers, but closer to the central seating position). This setup results in seven front and four rear speakers. While relatively few movies have been released in 11.1, some of these leading edge films include Rise of the Guardians, Man of Steel, The Croods, Elysium, Turbo, Ender’s Game, Mr. Peabody & Sherman, and How to Train Your Dragon 2.
