Acousticom manufactures audio communication equipment utilized by the Department of Defense and leading aerospace companies. The company is well-known for its flight helmets, but it is coming to CES 2010 with something almost everyone can enjoy--the Sound Egg.
The egg chair is back, but with a 5.1 Dolby Digital surround sound system and an intimate media experience not intended for sharing. The chair can be connected to a television or computer and its unique foam insulation means no more complaining from your significant other. Go ahead, play Call of Duty all you want--he or she won't hear a thing.
The Sound Egg was initially manufactured as a demonstration tool for trade shows. Although this is still a marketed use, Acousticom is making it available as a consumer electronics item. The $1,450 seat is not for everyone, but audiophiles might call it an "investment."

We've covered just about everything you need to know about the PS3 Slim, but the sleuths over at Engadget HD (via a translated version of AV Watch) found a chart that indicates the PS3 Slim can bit stream both Dolby TrueHD and DTS-HD Master Audio. That change actually isn't that surprising, since the original limitation on the "old" PS3s was due to an older HDMI chipset; newer HDMI outputs have no problem bit streaming the high-resolution soundtrack formats.

We have a PS3 Slim review sample onhand, so it was easy to confirm the rumor. We had the PS3 Slim connected to the Sony STR-DN1000 receiver via HDMI, and we loaded up "Appaloosa," which as a Dolby TrueHD soundtrack. After making a few tweaks in the XMB, were able to make the STR-DN1000's display say "Dolby TrueHD"--confirmation that the Slim was sending the soundtrack in encoded bit stream format. Next, we loaded up "Master and Commander," which has a DTS-HD Master Audio soundtrack, and that ... Read more
This is the ideal 7.1 setup, but very few home theaters really look like this.
(Credit: Dolby)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.

The CNET New York listening room, set up for the Dolby Pro Logic IIz.
(Credit: Sarah Tew/CNET)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
Atlantic Technology's new 1400 SR-z speaker was designed with Dolby's Pro Logic IIz "height" surround processor in mind
The new speaker's compact size and shallow profile allow it to be unobtrusively mounted high on the wall above the system's front left and right main speakers. The 1400 SR-z sells for $425/pair MSRP.

Atlantic Technology)
The company claims that the 1400 SR-z's "voicing" and timbre will match all of Atlantic Technology's speaker systems.
Each 1400 SR-z uses a pair of 3.5-inch full-range polymer-treated cone drivers. The wedge-shaped speaker disperses sound laterally and allows the user to select dipole or bipole operation to deliver an enveloping surround soundfield. The speaker measures 12.25 x 8 x 5.375 inches, weighs 7 pounds, and comes in an attractive satin black finish.
The 1400 SR-z will be available in May 2009.
With Pro Logic IIz some receivers will produce 9.1 channel surround.
(Credit: Dolby)The Dolby Web site is bubbling with excitement about its new processing trick, "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." The "z" in Pro Logic IIz signifies the Z axis, otherwise known as height.
Sounds interesting, but when I setup and listened to the first receiver (an Onkyo TX-SR607) with Pro Logic IIz, the height speakers didn't lift my spirits.
Pro Logic IIz can, depending on the receiver's capabilities, either augment a 5.1 or 7.1 channel speaker system with two height channels. In other words, in a 5.1 channel system with Pro Logic IIz you'll have five speakers in the front of the room--left, center, right, left height, and right height--plus a surround speaker to both sides of the main listening position.
The 7.1 system with Pro Logic IIz uses the same speaker array--plus two rear surround speakers.
Once you have a receiver equipped with Pro Logic IIz, and wall mount the height speakers three feet or higher over the main left/right speakers, you're all set. You won't have to buy specially encoded movies or music.
According to Dolby, "Pro Logic IIz identifies and decodes spatial cues that occur naturally in all content--stereo and 5.1 broadcast, music CDs, DVDs, 5.1 and 7.1 Blu-ray discs, and video games. Dolby Pro Logic IIz processes low-level, uncorrelated information--such as ambience and some amorphous effects like rain or wind--and directs it to the front height speakers."
Nice idea, did it actually work?
... Read moreThe first time I bought into this this whole digital 3D thing was a 2006 showing of "Superman Returns" on an IMAX screen. In the scene, various objects floated around the screen and seemingly, right in front of my face. For me, this was the first time 3D had lived up to its promise.
If Dolby Laboratories has anything to say about it, it won't be the last. On Tuesday, the company announced that theater exhibitors will now be able to play Dolby 3D Digital Cinema content on screen sizes of up to 70 feet (42 feet was the previous cap).

If you went to the "Jonas Brothers 3D Concert Experience!" on a 42-foot screen thinking, "You know that was cool, but I still have most of my face attached," just wait until a full 70 feet of pure Jonas Brothers rock completely melts your f#*@ing face off!

Dolby has a new surround format: Pro Logic IIz.
Here we go again. Another new format with more speakers, but this time, the "surround" speakers are in the front of the room, three or four feet above the left-and right-main speakers. These height channels are designed to provide a greater sense of envelopment than previous generations of Dolby or DTS surround.
With Pro Logic IIz, some receivers will produce 9.1 channel surround.
(Credit: Dolby)Pro Logic IIz incorporates all of the features and capabilities of Pro Logic IIx.
"Expanding on established Dolby Pro Logic II matrix-decoding innovations, Dolby Pro Logic IIz identifies and decodes spatial cues that occur naturally in all content--stereo and 5.1 broadcast, music CDs, DVDs, 5.1 and 7.1 Blu-ray Discs, and video games," the Dolby site further explains. "Dolby Pro Logic IIz processes low-level, uncorrelated information--such as ambiance and some amorphous effects like rain or wind--and directs it to the front height speakers."

You don't have to buy new, specially encoded discs to experience Pro Logic IIz, but do you really want to buy another pair of speakers, wall-mount them, and run a pair of speaker wires up your wall, to the sides of your TV?
Dolby doesn't require the height speakers to be identical to the main-left or -right speakers. Some Pro Logic IIz systems will use a total of nine speakers (five front, four rear), plus one or more subwoofers.
Onkyo's TX-SR607 ($599 MSRP) is the first receiver to feature Pro Logic IIz; the company will soon offer additional models equipped with the new Dolby processor, to be announced later this year.

(Credit: Onkyo)Then again, Yamaha's higher-end receivers have had height, aka "Presence," channels for years. Those extra speakers supplement the sound from the front speakers with ambient effects produced by Yamaha's proprietary Cinema DSP, which provides various multichannel configurations up to 11 channels. Obviously, Dolby's Pro Logic IIz uses different technology, though the end result may be similar.

The Onkyo TX-SR607 is the first AV receiver we've seen with a front panel HDMI input.
Sony and Yamaha have announced their midrange AV receiver lines, and today Onkyo announced three new AV receivers ranging in price from $300 to $600. The biggest news is that the new TX-SR607 ($600) will be the first receiver to feature Dolby ProLogic IIz sound processing, which can expand existing 7.1 soundtracks to 9.1, routing some of the audio to "front high speakers" which are positioned above your standard front speakers. Let's take a look at how all three models compare:
Key features of the Onkyo TX-SR307:
- 5.1 AV receiver with 65 watts per channel
- Three HDMI inputs
- Two component video inputs
- Four composite video inputs (no S-Video)
