There is no question that the subs made by REL, Velodyne, Vandersteen, and others are excellent, and the best for music. However, if you are on a budget, or want to try a sub without a high initial outlay of money, may I suggest the 12" Acoustic Research AR-S300? It is a powered sub with a built-in, 300-watt Carver Sunfire amp. The sub can be purchased for $400 (MSRP is $650), plus shipping, from an authorized online dealer, Accessories4less.com. I am currently using a pair of these subs with my Vandersteen 3A Signature main speakers, and am very pleased with them. They do a very good lent job with both music and video. The sub accepts several different methods for connection, has a crossover that ranges from 40-120 Hz, has a switch for both music and video (which changes the response somewhat), and is of reasonable size.
