Parts Express showed a prototype of a new subwoofer plate amp (available soon). It includes two separate amp channels, to separately power two subwoofer drivers in the same cabinet (with each amp rated at over 1200W into 4 ohms), or perhaps single driver with a slaved sub located elsewhere. The amps also offer DSP room compensation, and while it wasn’t yet clear exactly how this would be implemented or how extensive it might be, a microphone for it is included. Price TBD.
If there's one factor limiting the wider acceptance of front video projection in the home it's the need to view the projected image in a darkened room. I can't count the number of times I've seen visitors to various on-line forums asking how well this or that projector works in a room with only partial light control. In <I>every</I> case, the answer should have included (but didn't always), "Not nearly as well as it will in a totally darkened room." The simple fact is that video screens reflect light, and if that light comes from something other than a projector—a partially covered window, perhaps—the screen doesn't care. Stray light, reflected off the screen, will inevitably degrade the richness and depth of the image. At worst, it will make it washed out and unwatchable.
<I> In this guest blog, contributor Steven Stone looks at the Algolith Flea, a $995 outboard video noise reduction box. In the blog entry following this one, I take a look at the $2995 Mosquito, Algolith's most sophisticated video noise reduction device.
A recent posting here on Sound&Vision showed a very ambitious do-it-yourself speaker built by a skilled audio enthusiast in Latvia. The finished product was originally found by us here and originated on one of the most exhaustive and impressive loudspeaker DIY websites, troelsgravesen.dk.
One question in the posting’s comments section suggested that the roughly $5000/pair cost that would go into building such speakers (not including time and labor) might be better put into buying a finished pair of $5000 speakers...
Algolith's Mosquito is an outboard video noise reduction device that Algolith describes as an "analog and digital compression artifact reducer." At $3000, it may be the most expensive device of its kind offered to consumers. It may also be the most sophisticated. If you judge your audio-video components by weight, it won't make much of an impact. But weight has little to do with the performance of this sort of product.
The recent departure of Oppo from the new disc player landscape* has produced a flurry of “packaged media is dead” vs. “I want my video discs” chatter on the Web. It has also prompted me to ponder once again both sides of the question.
I don’t believe that Oppo’s decision has much to do with any sign that packaged media is likely to imminently disappear. Check the release schedules shown on a number of disc review sites (such as thedigitalbits.com) and you’ll see that dozens of titles are released each week. Some are new, some are re-releases, and many are unreleased movie titles dumped directly to video...
Pioneer's speaker guru Andrew Jones conducting one of the first Dolby Atmos demos in Los Angeles.
Things are moving fast on the Dolby Atmos front. Here's an in-depth look at Dolby Atmos—what it is and how it works—as well as my first impressions of recent demos conducted by Pioneer and Dolby Labs.
The history of audio and video, both in the movie theater and at home, has been a back and forth tug of war for decades. Stereo, for example, started in the theater and was only adapted to the home much later (a couple of decades later if you count Disney’s Fantasia as the multichannel theatrical milestone. But a small bump in the road they called World War II delayed the widespread theatrical adoption of multichannel audio, and therefore the impetus for home stereo, for years).
Digital projection also appeared first in the movie theater, followed soon afterword by affordable digital displays for the home. But as each trickle down from theater to home enhanced the home experience and therefore threatened the viability of movie houses, theaters and studios moved to counteract the threat. That gave us today’s enhanced (or at least louder!) multichannel surround theater sound, vibrating seats, widescreen films, high resolution digital projection, and last but least, 3D.
The best movie theaters are now equipped with every trick in the AV book...
A couple of blogs back I addressed the subject of Dolby Cinema, a combination of technologies, both audio and video, being promoted by Dolby as a dramatic improvement in theatrical presentations. They’re right. It most certainly is.
But first a little background. I stated in that other blog that Dolby Vision (which promotes a wider color gamut and high dynamic range, or HDR) was primarily developed for flat screen sets, which can produce greater brightness (practically speaking, up to around 300 foot-lamberts in an affordable consumer displaythough Dolby’s pro display can do much better at considerable cost). For commercial film presentations, Christie Digital has developed, in cooperation with Dolby, a new, laser-lit projector capable of 30 ft-L (in 2D and, of course, depending on screen size and gain).
If that doesn’t sound like a patch on 300 ft-L, keep in mind that most theatrical projectors are lucky to hit 15-16 ft-L (again in 2D, and far lower in 3D)...
