4" 40W SHIELDED WOOFER, 8 OHM

I bought two of these, and put them them in some really old Bose enclosures. They just happened to be a nearly direct fit, so it worked out pretty well. The bass response is fairly good, especially considering the size of these things. They are also heavy for the size. I think these would really sound great from a small quarter wave transmission line enclosure. If you do a google search for that, you should be able to find some info on transmission line enclosures.
