Thanks for the input so far folks. I never thought that the sub could be as important as you guys say. Ive heard some people believe that a person should get the most expensive sub they can afford. So these are my thoughts at the current time. I have a high quality 12" Kicker Solobaric sub in my car in a non-cube shaped box that I have built. The whole thing is extremely solid. I built my own enclosure as a trapezoid, since I heard that a cube is the worst possible acoustical shape for a speaker to be in. The box is sealed and is only .88 cubic feet, creating tight, punchy, not boomy bass. I dont know of its range or if it goes all the way to 20hz. Ive seen the majority of home subwoofers are ported enclosures that put out a lot of volume with a relatively small amplifier. What I am thinking of doing is using my car subwoofer in my home with a separate two-channel amp bridged down, or a good powerful monobloc amp. The problem that I see with this set up is that I will need about 350 watts rms, which could be pricey, and i wont have subwoofer controls on the amp. This doesnt seem to be a huge problem to me because I can control the LFE output on my receiver. What do you guys think of this idea? Reasonable, or just go with a good quality home theater sub?
