17' x 26', but that's deceiving. One long side is essentially a pathway to the back door. I have the speakers placed on a long wall, on either side of a fireplace centered on that wall. I would rather use the standard placement (narrow wall) but that just won't work in this room re: seating.
But this actually works out quite well. I have the Coherents mounted on 26" high stands, 8' apart (center to center) and approx. 30" out from the wall behind the speakers. When I received them the speakers were stuffed with polyfill fiber, which I removed. The speakers sounded a little too "polite" when stuffed, at least with the 45 tube monoblocks. If I were using a an EL84 or 6550 amp I would replace the fill if necessary.
I use two REL T5i subs. These are small, downward firing units that work great. I tried the larger T9s and prefer the T5s. The T5s are well made and are quite reasonably priced.
