Which subwoofers perform well with music? The use would be aiding a pair of bookshelf speakers. There are a lot of subwoofers out there, but many are made for home theater and are not always well-suited to music. Also, are there any cues about the best use for subwoofer from looking at its specs? I am not going to be purchasing one anytime soon, but I am curious as to which brands and lines are good for this use. Thanks.
