My living room, dining room and kitchen is all one big OPEN "L". The bottom short line of the "L" would be the kitchen area, the the corner of that then moving forward towards the center of the "L" would be the dining room, and rest (top half of the "L") is the living room. A sectional divides the LR form the DR, so the actual LR is about 15' L by 11' W, all with 8' ceilings, but overall the "L" is 25 L by 11' W, then it all turns into that kitchen (bottom of "L")
Man, that was ridiculous... sorry for all the "L"s. Lol.
Also, we have all hard wood floors, with the exception of a large area rug right where our LR is where the 5.1 would be. Plenty of cloth blinds, pictures, area rug, etc in LR to deflect reflections. Front 3 speakers would be all the way on top of that "L" and projected towards the bottom of the "L" being the DR. The sub MUST be in the middle of the "L", separating the LR and DR, which stinks, since it is not in any kind of corner and would just be against a wall, hiding behind the wedge of my sectional.
So yeah, I told you all this just in case we need it to determine which sub to go with. And yes, I live in a 2 story co-op, but there are no neighbors living downstairs for 2 years or more. Long story, they keep it as a huge storage. Weird. So, I'll have to turn her down eventually in a couple of years or so.
Again, thank you so much for your attention and expertise!
