Well, if you've heard them (I assume you have) and they are worth a little more expense and time, I'd buy some good 3-way binding posts and replace the funky modules. You'd need access to the inside obviously- the woofer might be the trick. Some older speakers actually could have the back opened up. It's an easy solder project (usually) to replace binding posts and the sonic upgrade is not minor, especially on older speakers. Here is a link to binding posts for sale online... http://www.madisound.com/cgi-bin/index.cgi?exact_match=yes&product=BP&cart_id=9987466.23945

Good luck
