oBravo Has Folded Tweeter and High Hopes
Mark Fleischmann  |  Jan 10, 2013
Every CES is loaded with exhibits from hopefuls looking to make their mark. Many of these tales of aspiration and struggle are never told. Let us say up front that Taiwan-based oBravo does not yet sell its products in the United States. However, its AI-25P powered sat/sub set got our attention with its folded ribbon tweeter, which produced remarkable detail with violin, acoustic guitar, and other stringed instruments. The 2.1-channel system including speakers, sub, compact amp, and dock would sell for $2500. Note that the dock has the 30-pin Apple connector but a snap-in module adapts it to the new Lighting connector.

HRT Speakers Have Blue and Air
Mark Fleischmann  |  Jan 10, 2013
"Blue" and "Air" has become our notebook slang for products including both Bluetooth and AirPlay wireless capability. There are quite a few of them at this CES. HRT, a new company, features them in the Stage speakers, with analog amplification, preamp, and USB DAC built into a separate module. One-inch tweeters are treated fabric, 3.5-inch woofers are aluminum, and the system sounded fabulous with CD-resolution files of Miles Davis' Kind of Blue (and we think it could have sounded even better with a 24-bit file). The price is $999 with Blue and Air or a hundred bucks less without—but why would you do that? Shipping in June.

MK Bows New THX Subs
Mark Fleischmann  |  Jan 10, 2013

MK celebrates its 40th anniversary with three new THX-certified subs, all with dual drivers in a push-pull configuration that has the front-firing driver operating in phase and the bottom driver operating out of phase, as shown in the brochure we photographed on our hotel room bed. Each driver is in a separate chamber with electronics in a third one. Driver sizes are reflected in the models numbers: X12 ($3200), X10 ($2600), and X8 ($1900). Rated power is 400 watts RMS and 700 watts peak for the X12, 350-650 for the X10, and 300-600 for the X8. Shipping between February and April depending on model. Fans of the venerable MK 150 might want to given a listen to its new tweeter.

Sherwood Unveils Six Receivers
Mark Fleischmann  |  Jan 10, 2013
There weren't many surround receivers on the floor of the Las Vegas Convention Center, but Sherwood was a hardy exception, showing a half-dozen new ones shipping between April and May. The top-line model is the R-977 with a rated 145 watts times seven into six ohms. It features Anchor Bay video processing, internet radio with vTuner, DLNA, direct USB connection of iOS devices, and a phono input. Perhaps more interesting is what's missing: Sherwood is no longer the lone receiver brand supporting innovative Trinnov room correction, a prominent feature of the old (and more costly) R-972. Instead it is relying on the proprietary SNAP room correction that it has also used previously. Price is $1000. At the opposite end of the line is the 5.1-channel RD-5405, selling for a mere $170.

THX Shows New Certified Products and More
Mark Fleischmann  |  Jan 10, 2013
THX had a lot to talk about. Tascam is a new brand among THX-certified receivers with the PA-R200, shipping in January for $1299. It is THX Select2 certified. The German manufacturer Teufell has earned THX Multimedia certification for the G850 satellite/subwoofer set, including a dual six-inch sub said to reach down to 35Hz. It ships in February or March at a price to be determined. The first THX-certified (for video) 4K display is the Sharp LC60HQ10, a Japan-only model. Finally, a pair of A/B demos showed the fruit of THX's collaboration with Sontia on a means of correcting acoustic defects in loudspeakers, as opposed to room correction or other forms of DSP magic. With satellite speakers the SPT Optimized version had noticeably greater bass extension. With monitors, there was better focused soundstaging and more detail, though also more brightness, that last part not necessarily an improvement. Initial applications would include soundbars and other products where speakers are matched with amps.

DTS Does Something Amazing in 11.1 Channels
Mark Fleischmann  |  Jan 10, 2013

DTS offered one of the show's more interesting audio demos with DTS Headphone:X. The audience were given Sennheiser headphones selling for roughly $100. With headphones off, we heard an 11.1 channel check with front, front height, center, side surround, back surround, and back surround height channels (not including sub). Then the channel check was repeated with headphones on. It sounded precisely the same and the sound still seemed to be coming with the speakers. Finally we were invited to hear the channel check while removing and replacing the headphones. At this point it became clear that the sound was coming only from the headphones. The steering was impressive, with the side, back, and height channels occupying their places in the soundfield with the same confidence as the front channels. DTS also did an A/B demo of the Vizio VHT215 2.1-channel soundbar with various technologies acquired along with SRS Labs. Even amid the noise of the show floor, it was clear that what is now called DTS TruSurround (formerly SRS TruSurround) was lifting the soundstage clear of the bar's physical limits. Just a little, but enough to be noticeable.

CES 2013
Revel's Got Rhythm
Mark Fleischmann  |  Jan 09, 2013
The Revel Rhythm2 has an 18-inch aluminum driver with four-inch voice coil backed up with 2000 watts. Of course like any state-of-the-art sub it can be room corrected via USB, in this case with a third-party measuring tool. But this one is slightly unusual because it takes into account the bass output of the speakers as well as that of the sub. The demo was impressively powerful though marred by an unavoidable rattle in the room ventilation—if you want to own a sub this powerful, you may need to invest a little extra to make the room fit for it!

Tannoy Gets Precise
Mark Fleischmann  |  Jan 09, 2013
Tannoy's new Precision line includes continues to use a coaxial array—the company calls it a dual concentric array—with the tweeter mounted at the center of the midrange driver. But this new version is revoiced for greater efficiency and dynamic range. The line includes the Precision 6.4 tower, $3200/pair; the Precison 6.2 tower, $2400/pair; the Precision 6.1 monitor, $1200/pair; and the Precision LCR, $1000. All have six-inch woofers, hence all the sixes.

Meridian Gets into Walls
Mark Fleischmann  |  Jan 09, 2013
Meridian's first on-wall speakers include the DSP 520 ($5000/each) and DSP 648 ($7000/each). Unlike most in-walls, but like other Meridian speakers, they are self-powered and loaded with DSP magic. They're also built with separate enclosures for the drivers, the electronics, and the back box. Our exclusive closeup shows buttons your installer can use to dedicate the speaker to left, center, or right channel use. Mount Meridian's Media Controller 200 to the back and you can control the system from your iPad.

Polk's Compact Wireless System Is Different
Mark Fleischmann  |  Jan 09, 2013
A lot of compact wireless audio systems have crossed our desk over the last few years but the forthcoming Polk Woodbourne, named for a neighborhood in the company's native Baltimore, is different. It has a fiberboard (not plastic enclosure) and the enclosure is sealed (not ported). Wireless options include both AirPlay and Bluetooth apt-X. Power is 70 watts RMS for each woofer and 20 for each tweeter. The demo was impressive for its spaciousness, thanks to the outward-aiming mounting of tweeters on the far sides of the curved baffle. We could close our eyes and imagine we were hearing a larger system. Pricing will be $599 when it arrives between April and June. Polk also showed the new TSx series which replaces the TSi. There are three towers, two monitors, and two centers in cherry or black. Woofers are polypropylene impregnated with other materials so that the intrinisic resonances of any one material are canceled out. Their size has increased in the towers and the larger center from 5.25 to six inches for bigger bass. Pricing ranges from $199 for the smallest center to $999/pair for the biggest tower.
