The DIY bug has bitten me and has done it hard. Right now i own a SVS PCI 20-39. I am happy with this sub but i feel like there has to be something better out there. The sub is used mainly for Hometheater but when I through parties it is used for music. The room size is fairly large, 20 x 30 or around that size. The one section of the back of the room opens up into the dining room. Directly below the room is a basement, i am sure sound blows through the floor, not sure if this effects the room size or not. The reciever that sends the signal is a denon 3802. I have a klipsch RC-7 center, and Wayne Jasekes Vertias for fronts. I bulit my sourround speakers but i forget what they are. Is there a sub out there that can beat my svs? Size does not matter. Price well it all depends on how much it is. Right now price really does not matter as long as it is resonable, $700 or so for driver and amp wouldn't be bad. Can anyone offer suggestions? Thanks a ton. If you have any more questions please ask. I love to feel the bass when the movie or music calls for it. But i hat e when it hums during scenes that have bass but only sounds like a constant droning.
