Ok, I have a HT setup, with 4 B&W DM303's and the matching center channel, and an SVS sub (one of the older ones), but there really isn't any woofers anywhere. The sub works fine for the low frequencies, and the other speakers are good for what they do, but music just doesn't sound right. Any suggestions to add a bit of mid-bass somehow? I could get a set of DM603's, but then it'd mismatch the rest of the system. If there were speakers with woofers in the DM300 range, I would have gotten those for the fronts. The 603's are $1000 which is a bit more than I want to spend. Is there such thing as stand-alone woofers? Should I get some small subs? Buy some 603's off eBay? Any other ideas? Thanks.
