It's really hard to quantify how much bass I'm looking for, but I will do my best to describe it.
I don't need room shaking, pictures falling off the wall bass. I'm looking for that nice, crisp, deep, and clean bass that you get in your car from a higher end 10" sub. Nothing muddled or very boomy, just precise and clean. I wouldn't mind if my couch vibrated a bit during explosion scenes or bass heavy music.
The whole first floor is open. The darker bold lines are walls, but the only place you can be in an enclosed space on first floor is the bathroom or one of the storage closets.
Admittedly, the logitech z2300 sub was not optimally placed for the loudest bass possible. I put the speakers on the mantle (see floor plan) and the sub just to the right of thr mantle on the floor about six inches from wall and about 3.5 feet from nearest corner. I had a feeling that the vtf3 wouldn't be quite enough sub to pressurize such a large area. My next question is...dual vtf3, single vtf15, or dual vtf15?
