Hey all! I'm hoping to gather some data here and determine the most popular sub out of these choices. I have a pair of AV123 ELT525M's on the way and I need to order a sub soon! My MAX budget is $300 shipped. My listening preferences are 50% music / 50% movies, and it will be hooked up to a Onkyo TX-SR506. My room is about 13ftx13ft and I don't want to use paypal/ebay.

Some facts:

Velodyne VX-10: 36-120 Hz +/-3dB, 2" Voice Coil, 100 RMS, 35lbs, coated fiber cone
Acculine Asub: 25Hz-150Hz, 3" voice coil, 125 RMS, 56lbs, paper-composite cone
Klipsch KSW-10: 29-120Hz (plus/minus 3dB), 55 RMS, 29lbs, fiber composite cone
Energy ESW-10: 27Hz-120Hz +/- 3dB, 100 RMS, 28lbs, High Excursion Injection Molded Cone MMP
Cadence CSX-12: 25-500Hz, 2" Voice Coil, 150 RMS,

Thanks and happy voting!
