Curt, I'd appreciate feedback on the following plan for speaker placement.
The surrounds are now as shown in the pic; left side speakers mirror the right.
I put the side surrounds where they are because it's close to what the ITU/972 manual recommends, and so Trinnov wouldn't have to work so hard to re-map them.
But now, after your additional explanations and ensuing discussion, I wonder if a more useful way to think about it is that Trinnov will try to create phantom images where they belong over 360 deg azimuth (not sure about the very back though).
Therefore it would be better to have more even angular spacing of the surrounds, which I could do by moving the sides from the back edge of the fireplace to the front.
Is that about right?
Another possibility, which would give me back two of the speakers I removed after the Denon 4311:
- Use a phantom center to free up one channel (assuming I don't have the same issue as Chris).
- Connect the two surround back speakers to one amp channel, freeing up another one
- Use the two newly available channels for a pair of front speakers, located at the former Audyssey DSX wides' locations at 60 deg azimuth from the center speaker and about a foot above ear height, or at the former Audyssey DSX heights locations' at45 deg azimuth from the center speaker and 45 deg elevation from the listening position (see pic), or somewhere in between.
Speaking of height channels, the user notes say
"Trinnov 9.1 with height
Some of you want more channels, up to 9.1- typically to fill in long rectangular rooms. The best way to accommodate
more channels such as 9.1 is to share the side outputs with two speakers each, thereby leaving the rear outputs for use
as height channels in the front."
To be clear, this is intended only to correct soundstage height errors, as with a below-screen center speaker, not to expand the soundstage height as with DPL IIz or Audyssey DSX - right?
