Zvox's biggest, best-sounding TV speaker

Sound bar speakers vastly simplify home theater setup and installation, but their sound quality always falls short of bona fide 5.1-channel speaker-subwoofer-based systems. The single-box Zvox Z-Base575 get closer to that ideal than most.

The problem with sound bars is they're too small. Even pricey bars like Yamaha's YSP-3050 ($1,199 MSRP) can't generate full-blown home theater impact. And it's a bit bigger than average (31.5 inches wide by 6.1 inches high by 6 inches deep), but films like "Mission: Impossible III" sound tepid over the YSP-3050. The film's explosive effects lack the excitement you'd get from a 5.1 system. Yamaha's technology is amazing, but it can't produce high-impact sound from skinny cabinets. I'm not singling out Yamaha here; Denon, Marantz, Polk, Samsung, and Sony sound bars all--to varying degrees--squash dynamic range of movies.

Stepping up to the YSP-4000 ($1,600 MSRP) won't make that big a difference; in my CNET review I noted that it stumbled with big special effect-driven flicks like "Mission: Impossible III." The explosions fell flat, the bass was rumbly, and the Yamaha couldn't play loud at all. Hooking up an Acoustic Research HT60 subwoofer to add extra muscle helped a little, but the YSP-4000 still lacked punch.

Part of the problem is that almost all sound bar speakers are too small. Zvox's Z-Base575 is big and very, very deep. How deep is it? Sixteen inches! So unlike other surround bar speaker systems that can either be wall-mounted or set on a shelf, the Z-Base575 was designed to be used as a base under your TV. Don't worry, the sturdy medium-density fiberboard cabinet can support heavyweight displays. … Read more

Fun with feng shui

MB Feng Shui Bagua is a fun, easy-to-use bit of freeware that helps you apply the Chinese system of feng shui to your own home. The simple graphic interface takes you step by step through the process of mapping your home, including all the rooms and doors. The program then breaks the area into "bagua" to give advice on everything from furniture to colors.

Although the graphics are rudimentary, most users should be able to re-create their homes fairly accurately. We had some problems with things like multiple floors or rooms that weren't symmetrical, so it would … Read more

Are SACD and DVD-Audio dead yet?

It's interesting. Tens of millions of homes are equipped with multichannel home theater systems, but multichannel music is a dead issue. Stereo rules the roost, for going on 50 years.

Ten years ago it looked like stereo's days were numbered--the two new multichannel formats, SACD and DVD-Audio, were on track to be the next big things. Funny, it didn't work out that way. I cover the subject in detail in my "Whatever happened to 5.1-channel music?" article that appeared in the July issue of Stereophile magazine.

Obviously, 5.1-channel sound makes sense for movies and home theater, mostly because 5.1 was an outgrowth of theatrical film-sound technologies stretching all the way back to the 1950s.

Every attempt to bring surround music into the home without video has flopped, big time. Are you old enough to remember the rise and fall of quadraphonic in the 1970s? What was needed was a surround format that didn't require music lovers to invest in new playback gear. Surely such a format would prove the viability of music surround...wouldn't it?… Read more

Do you use all seven channels on your home theater receiver?

An industry insider recently admitted to me that only 30 percent of AV receiver buyers ever bother to hook up all seven channels to their receivers. That guesstimate seems a little high to me; the standard 5.1 channel setup: Left, center, right speakers upfront, and a pair of surround speakers to the sides of the main listening position can supply a truly immersive sound experience.

Seven-channel home theater adds two more speakers, placed behind the main listening position. That's tough to accomplish in rooms where the couch or chairs are up against the rear wall. There's no "rear" there, so some folks mount the rear speakers up high, or bounce the sound off the ceiling.

Still, the rear surrounds typically contribute little, so it's pretty hard to justify the added expense and hassle of running the extra wires for a marginal sonic improvement. The one exception might apply to very large rooms where the side and rear surround speakers are further apart from each other. The extra coverage may produce a more complete sense of surround envelopment. … Read more

If your PC is pulling double duty as a media center, I can't speak highly enough of the Logitech Z Cinema speaker system. It's a 2.1-channel surround-sound powerhouse that cranks out 180 watts and comes with a sweet media-center remote.

Originally priced at $300, the Logitech Z Cinema is on sale for just $79.99 from TigerDirect. Shipping runs a hefty $22, but that's understandable; these are hefty speakers!

The system consists of a subwoofer that plugs into a USB port and two desk-friendly satellite speakers. On one of the satellites you'll find both headphone … Read more

Dolby Pro Logic IIz: Taking a second listen

Recently, Steve Guttenberg, our resident audio guru, took a listen to the first AV receiver to offer Dolby Pro Logic IIz. And he wasn't impressed.

Pro Logic IIz is the latest surround format from Dolby Labs. This one utilizes "height speakers" placed above the left and right front-channel speakers. The configuration Guttenberg tested utilized a 7.1 configuration (a standard 5.1 setup, plus 2 height speakers), but Pro Logic IIz is designed to support 9.1 as well (7.1 plus 2). That will presumably be supported in future

According to Dolby's Web site, the advantages of Pro Logic IIz are as follows:

With Dolby Pro Logic IIz, rain in a movie now seems to be actually falling on the listener's roof, concert videos bring a more intense sense of being at the performance, and orchestral works deliver more palpable depth, power, and connection.

In games, the added dimension increases the realism and immerses players more deeply than ever in the action.

Because it processes only nondirectional sounds for the height channels, Dolby Pro Logic IIz maintains the integrity of the source mix and the effects are always appropriate to the material. The added dimension complements the sound from the rear-surround speakers, adding spaciousness while honoring the original intent of the content creator.

Alas, Guttenberg could barely hear a difference when Dolby Pro Logic IIz was engaged: "The height speakers didn't make a discernible difference. I couldn't hear them at all, so I increased the height speaker volume by 3 decibels. Still no difference."

Needless to say, Dolby and Onkyo (the maker of the TX-SR607, which is the first IIz-compatible hardware) weren't too happy with that evaluation. So, we told them we'd give it a second chance, with more ears in the room.

For Round Two, Steve Guttenberg (again), Executive Editor David Carnoy, Senior Associate Editor Matthew Moskovciak, and I crowded into the CNET audio room.… Read more

Mitsubishi LCDs get 16 speakers apiece

Update 12/21/2009: Since this product preview was written, CNET has reviewed the highest-end member of Mitsubishi's Unisen line, the LT-249 series. It features 2 more speakers than the 151 and 153 series described below, and also includes a few other enhancements (namely support for Vudu), but we still expect its audio and video quality to be very similar to the step-down models. For more information, check out the full review of the Mitsubishi LT-249 series.

Not to be outdone by LCD TV makers touting LED backlights, 240Hz refresh rates, and stratospheric prices, Mitsubishi brings its own twist to the game of HDTV step-up-oneupsmanship with its Unisen models, each of which sports a new 16-speaker audio system.

Nestled below the pursed lips of the simulated image above, you'll find 16 speakers, an array that even when turned off should impress visitors to your living room.

When turned on, according to Mitsubishi, the "intelligent speakers...direct perfectly balanced audio waves beside and behind you to reproduce 5.1 surround sound and create an unprecedented depth of sound experience." We haven't tested the system, but on paper it sounds a lot like the principle employed by virtual surround speakers like the Polk Surround Bar.

If Unisen performs as well as such speaker systems, it will certainly represent the best TV sound we've ever heard. The question, of course, is whether it's worth it. The Polk bar above costs about $1,000, and less expensive options like the Zvox 325 ($299) are also available that do a solid job of simulating surround.

Then there's the myriad true surround systems out there with actual rear speakers--although they're not direct competitors to Unisen, since the biggest benefit of simulated surround is lack of rear speakers, wires, etc.

Mitsubishi's three series of Unisen models include 40-, 46-, and 52-inch sizes, and the least expensive, the 40-inch LT-40151, costs a suggested retail price of $1,799. Compared with competing 120Hz LCDs, like Samsung's LN40B650 ($1699) or Sony's KDL-40V5100 ($1499), that's not a massive premium.

On the surface, Mitsubishi's new sets look pretty appealing for people who want better sound from their TVs, and perhaps the company's picture quality has improved over last year's models, such as the LT-46148. We'll know more when we can get one in for review.

All of Mitsubishi's Unisen models will be available in May. Pricing and step-up details follow.… Read more

Samsung HT-WS1: Budget sound bar speaker

Considering its full plate of goodies--built-in Blu-ray player, iPod dock, and the capability to stream Netflix movies and Pandora's online music service--the $800 price tag on Samsung's HT-BD8200 sound bar is quite reasonable. But that's not to say it won't be a tough sell in these economically anxious times. And that's where the new HT-WS1 comes in. The smaller sound bar is strictly audio-only--no Blu-ray, no DVD, no video connectivity whatsoever. It's more of a glorified TV speaker, accepting either an analog stereo or digital-optical input (it can decode standard Dolby Digital and DTS … Read more
