He he, thanks for the compliments.

It's best to have the IB centered between the mains or two IB's, one next to each main. The best way to "check" your IB location to be sure the seating area isn't in a null etc... is to put a box sub where you'll be sitting and then measure the response from the location you intend to put the IB. Mine measured decently but not as good as other parts of the room. I opted for the prime location between the mains even though the response was a little weaker than other places. I have been able to overcome the weakness of that spot with EQ though.

The center channel is only about 2.5' above the screen and slightly forward. The dialogue sounds just as if it is coming from the screen, the only problem is there is little to no baffle step loss so some frequencies are a bit enforced which can cause certain voices to sound a bit tinny. I'll be upgrading the network on the center to account for no step loss which should bring the voices back to normal. Really though, it is not all that noticeable. I'm just a bit of obsessed with getting things as good as I can get them.

I have several response graphs but am in the middle of more tweaking. I'll post my updated graphs soon!
