I just finished rebuilding a pair of Sansui's - mine were a 12" 4 way design. I pulled all of the drivers and x-over, installed a new baffle and built a 8" 2-way system using a basic single order x-over I built from scratch. I had to stuff the cab with added foam, and did everything from trial and error. The result is perfectly adequate, but not state of the art. I also refinished the cab's with tung oil after sanding the veneer really well. They came out looking far better than I expected and I'm very happy with the result given what I put into them. I sold the woofers on Craig's list for what I paid for the speakers. No luck yet selling the other drivers though I haven't tried hard.
Rebuilding old Sansui's
I have an old set Sansui speakers from the late 60's or early 70's; the one's with the carved wood grilles, 14" woofers, 5" midranges, piezo tweeters and horn midrange. They have a really substantial cabinet and I was thinking of rebuilding them as a bedroom set.My thought was to keep the horn midrange and tweeters, and replace the crossover, woofer, and cone midranges. Any thoughts on this and if you think it's a good idea, where would I get high quality cone speakers and a crossover?
