"ONE digital sound projector is all you need for 7-channel surround sound -
no speakers required, and no wires all over. It's self-amplified. It learns
the layout of your media room.

"Talk about a strong list of features: check out our new PDSP-1 Digital
Sound Projector:

500-watt digital sound projector with 254 individual speakers, each with
its own compact digital amplifier.

Direct digital connection from a similarly equipped DVD or CD player

It perfectly projects up to seven separate sound beams containing
surround sound information (such as Dolby Digital) to pinpoint locations in
your media room

We mean YOUR media room. It can be programmed for room size, texture of
the floor and walls, and even whether the curtains are open or closed.

No need for an A/V receiver, outboard amplifier, or any other speakers

Only 5" thick

The proof would be in the listening.

Reminds me of the Sweet-16 speaker construction project; some audio mag
in the 1960s. The point of that project was to take 16 speakers of
medium to junk quality and blend the output in an array such that each
speaker had so little drive, distortion was kept to a minimum and the
cones coupled for better base.

Makes you wonder how 254 mini-cones can beam anything other than a
blended sound with minimal frequency response. Even low distortion
should be a problem with cones that look like their about 1" diam.

You mean in quality? Yep. I wondered about that - only applications so far
seem to be in spot art/museum gallery commentaries and vehicle cabs.
Yet if we are talking difference tones low frequency results may depend on
accurate source stabilities. Perhaps the Pioneer is sizzleware so far but
perhaps again the desired results may yet be achieved - time will tell.
I'm sure that's the technology behind the concept though. Steering and all
with 5.1 from one "source" is an ambitious take on it however; good on them.

The paranoiac mind-control conspiracy folk are of course already freaked
about the technology to make one person in a loose group hear voices ...

Nothing obvious here to me or even proof that it works. Any beaming is
either going to require a moving speaker or a cylindrical array of
speakers. The Pioneer is neither.

The US patent office too often issue patents for ideas that don't work.

Not required. It can be a phased array, which is pretty much standard
in modern military radar antennae, and allows much faster beam
steering than is possible with physical movement.

Very interesting and I just learned something. Do you think the
technique can be applied to the frequencies of audio and still be valid
and effective?

Nothing obvious here to me or even proof that it works. Any beaming is
either going to require a moving speaker or a cylindrical array of
speakers. The Pioneer is neither.


Not required. It can be a phased array, which is pretty much standard
in modern military radar antennae, and allows much faster beam
steering than is possible with physical movement.

Very interesting and I just learned something. Do you think the
technique can be applied to the frequencies of audio and still be valid
and effective?
