I am thinking to buy a subwoofer to match my receiver Yamaha RXV2400. My list are the VELODYNE CHT-12, JMLAB CHORUS SW700, PSB Subsonic 6i and the Yamaha YST-SW1500. Anybody can give me suggestion for the above sub and which one the better for my Yamaha ? Oh yes, my listening maybe 50%/50% for music and home theatre. Thanks alot all of you guyss.......
