I will be placing it to the left of the couch which is about three feet from the left wall in the room. the side surround is against the wall on a stand and the sub will be in front of the stand. I talk with Chad from Epik today and he said the Sentinel will go down to 14 or 15hz in room. That's what frequency response he gets inside. Pretty sweet. The FR on Epik's page is an outside freq resp not indoors. I would get two of them but only have room for one. wouldn't mind one on each side of the couch though but the right side is the walkway to the front door.
