Wow, that's a nice large space. What is your total budget and are you looking for a pair of subs?
Subwoofers
I'm looking at subwoofers, my speakers are Sonus Faber Olympica III. I have looked at a lot of subs to the point of overloaded. I'm leaning toward REL S812 X 2 due to room size. My living room, kitchen and dining room are open with a 24 foot vaulted ceiling, area is 35 X 25.
JL Audio, Rythmik, PSA, HSU, to name a few have been checked out.
HELP!
