I am actually trying to improve on a china made stereo speakers I bought a year ago. The baffles are good (rigid and well-made), however, the x-over and woofer are really bad. I replaced the paper cone tweeter with a metal dome the same time I bought it a year ago. By the way, I replaced the x-over network just this afternoon. I used a 2 way x-over from Crown (China) and I am happy to say that it sounded a lot smoother and sweeter after that. What concerns me now is the 6.5" woofer which are hardly making that "bass" sound. I owned speakers with tinier woofers that made better bass sounds. The present woofer makes very little cone excursions (as if they are too stiff and rigid). Any suggestion for a replacement woofer (locally available please). I once assembled a tapered pipe speaker system using Magus brand woofers (6.5") whose cone material resembles that of kevlar and it sounded really good (loud, soft, extended bass). They are no longer available. Any suggestions for a good woofer?
