The Beyma woofers I heard were well made, but "rougher" sounding than JBL 2226H woofers. IMO the JBL has little if any coloration, and it's easy on small tube amps. I think Eminence makes some good woofers like the kilomax series. Some people like TAD. I am told that McCauley woofers are excellent too. Anybody care to comment on either? Steve
