Jeff - The DSP has 4 different settings: 1 near, 2 near, 1 far and 2 far. I have the DSP set to 2 Far for the 39 inches. "1 near" allows for placement at close as 8 inches with little to no loss of the depth that the design offers.

Another thing to consider is, for such a large space as yours, how powerful the LFR-1100's are.

If you get "serious" about ordering a pair, I recommend calling Debbie and asking her to work with you on pricing. For the higher end systems, she is your best bet to get the best available deal.
