both of them cost about the same, and from what I read they can play way down to the 20hz range, the SVS is only 320w but the Titanic is 500w, both of them are capable of 110dB at 25hz, have any of you ever compare them? which one is more suitable for music, which one would you chose and why? By the way, the Part Express's 12" TITANIC MKIII SUBWOOFER KIT is $539.00, and SVS is $599. If I were to get the SVS brand new, where else can I get it cheaper?
