I can't spend a lot- was thinking of getting a $100 sub for now and later upgrade to an SVS or HSU later on after trying out a sub. This will be my firt sub ever! I have a height limit of 16 inches for the sub, so the SVS is out for now anyway. The $100 sub was just to have something in the meantime. I was thinking of the DLS 10" POWERED SUBWOOFER SYSTEM for $100 (someone here at HTF said it was pretty good as a starter). You can find it at the partsexpress web site. Its said to have: "...a 12 dB electronic low pass filter that is continuously variable from 40 to 160 Hz. It also features a 6 dB high pass filter (125 Hz, 8 ohm) output for satellite speakers. * Frequency response: 30-160 Hz ." One question: So how low does this go? 40Hz or 30Hz? Obviously I'm new to all this. Another inexpensive sub I heard about was a AUDIOSOURCE SUB (15" I think) that would need some extra poly fill. And finally I ask about this one (Which I think may be the way to go but then I hope not to upgrade at all): The 10" TITANIC VANCE SUBWOOFER KIT from partsexpress. At $350, is this a good buy? I know most of you will say save up and get a monster, but I want the sub NOW! One more Q: Will prices on subs drop after christmas?
