Also, even if I got audio to the receiver through this method speaker distance is still an issue. Wouldn't the positional audio be better if I had near-field speakers placed close to me versus having regular home theatre speakers placed all around the room?
My thought was to really mimic older traditional pc speaker systems that could be placed on your desk. I remember having a set a long time ago and it did rather well in terms of positional audio.
That is what Audyssey is for, the DSPs adjust and compensate for the speaker positioning delays, wall reflections etc for each individual speaker.
This allows the use of the fronts and center on the desk and the surrounds on stands.
Audyssey plays a series of calibrated test tones thru each speaker and a microphone plugged into the receiver listens for the response, this receiver then calculates the correct compensation curve for each individual speaker.
As the receiver listens for the speaker+room response, it deals with near field speakers quite nicely. I have the Audyssey microphone take samples in 3 locations around the chair at ear level about 12" apart
Positional audio is just awesome once the system is calibrated for phase and positional delays as well as the different speaker responses.
Similar tech in this area is made by Dirac and Trinnov.
