John,
thanks- Im envious of the wiring too. Thats not my work, thats just the result I desired. My installer did this, in particular one of his guys: Ken. Ken is a true artist as you can see. They do work all over the US............

Ronnie,
Interesting, what do you mean by metal radiators? I have no such radiators in my room. All the HVAC is in the floor- so we could really limit the openings in the side walls and ceiling. As such, there are no metal radiators any where near by the fronts. In terms of placement, its largely dictated by the screen. I did try experimenting with the available positions and I cannot get it any better than I have it. I would agree that more distance from the side walls would be preferable.
How big is your room? You must have a lot of space because with the 8000s set to free the bass was so tremendous that at moderate volume levels I thought my heart would cease beating!
Interesting about the toe in for the rears. I ruled this out as the rears are supposed to produce a more diffuse sound and I feel toe in for them would likely ruin the surround field for the rear seats in the theater.
Btw- on the toe in on the fronts- thats a suggestion I adopted from fellow Hitchhiker Gages.
So like anything else that theater is the culmination of years of living and learning from all sources especially fellow Hitchhikers.
best regards,
Jerry
