Hi, I was just wondering if anybody thinks that the new subwoofer kit that partsexpress sells: the 15" TITANIC MKIII SUBWOOFER KIT (Part Number 300-764) is tough to beat for $688 shipped. Here are the stats on the Titanic MKIII woofer: Power handling: 800 watts RMS/1,100 watts max Impedance: 4 ohms Fs: 19.93 Xmax 20.5 mm Sensitivity: 91.7 dB 2.83V/1m Vas: 7.79 cu. ft. Qts: .38 Here are some stats on the sub amplifier: High power Class AB output stage Patented tracking downconverter power supply Full parametric bass EQ Phase reversal switch Auto On/Off Advanced soft clip circuitry Toroidal power supply transformer Power output: 512 watts RMS @ 8 ohms, 1024 watts RMS @ 4 ohms S/N ratio: 98 dB (A-weighted) Low-pass crossover: 30 - 200 Hz, 24 dB/octave Auto On/Off Given that the sub has to be about the same size of about 20" cube, it seems like it would be tough to beat this sub for $688 shipped. The only SVS in this price range and size is the PB1-ISD, but it seems the 15" titanic could beat it hands down in displacement and power. Right now I have 2 tempests... This sub will be for a friend who has a room that's about 17'L x 15'W x 8'h. I've heard good things about the Titanic driver and I predict it should sound similar to a small sealed tempest. Any thoughts before my friend gets one? oh, BTW I'd go DIY, but the box alone would cost $350 which is why I believe that this sub kit is a better route.
