Thanks all for the information! I have a big open room, with family rm and dining room in one big space. Family rm is about 20 x 26 and is 20 x 40 with the dining room....BUT, and maybe a huge issue, I cant pull the speakers away from front wall more than a foot or so. I’ve got 3 or 4 feet on either side, with an 8 ft separation between existing spkrs, and an 11 foot coughered ceiling in the family room that reduces to 9 ft in the dining room. Bass boom could be an issue...yes?
