Eldartford, I read you on the advantage of having a centre channel. That this channel should use the same model speaker as the main l/r and same amplification makes sense to me. Have always been intrigued, however, on whether the ITU's recommendation that all five speakers be identical "full-range" and use identical amps is not first, premised on what the ITU considers to be "full-range" (I have never gotten an answer on that one, but think they see speakers used in the home as way smaller than what a lot of audiophiles use) and secondly, on some sound if rather impractical notion of uniformity. I am now thinking of putting together a multi-channel system as a second system using what I have on hand (Sony SCD XE 670, Yamaha MX-35 amp, four small Infinity speakers and two small Mission speakers) and getting low priced equipment to fill in those other spots (sub and centre channel) while things get sorted out in the marketplace.
2+2+2 Multichannel
I just bought two DVD-A discs put out by a German Audiophile recording outfit called MDGD. They use the six available channels differently.
They use the Left and Right, Front and Rear channels in the usual way. But then they call for two additional front speakers, located above and outside the regular front speakers. These are driven by the Center and Subwoofer channels. It is all supposed to produce a "3-dimensional" sound field, with no particular "sweet spot" for listener location.
I have not yet had the time to jury-rig this setup. The printed material that came with the discs does not provide much in the way of description of this 2+2+2 scheme. Does anyone out there have any info?

Well how about this Unsound, http://www.highfidelityreview.com/news/news.asp?newsnumber=19438410 Dave |
Unsound...Although a discrete center channel signal is best a logic-assisted matrix center channel can be darned good. Getting four channels out of two was too much to expect, but three out of two is quite reasonable. My surround sound processor has a 3-channel mode which I use when playing 2-channel material. Of course this involves digital processing, but when I am already working with digital inputs from a CD I don't see this as a problem. Although I have not heard it there is a purely analog three-channel decoder available. http://www.sedonaskysound.com/trinaural_processor.htm |
