Hey!!! This is my first message on HT forum, so I hope someone will help me out Anyways, I would like to add a second subwoofer to my system, which is: HK AVR 525 Sony DVPNS-715p Polk audio Rti70 front speakers Polk audio R50 for back Polk audio csi40 center chan. Polk audio psw202 sub So anyways, I thought of Velodyne CHT-12 or Boston PV 800. I work at Future Shop, so if I go with the Velodyne, I'll get it for under 600 (tax in + a 9 year warr.) The Boston (750 + tax) sounded very nice, but the Velodyne is better in specs. What would you recommend? HT forum kicks *ss!!!
