I have an old pair of NAD speakers and would like to replace the woofers, but of course NAD no longer makes speakers or replacement parts. What I'm wondering,is it possible to refit the woofers and/or the tweeters with different brand parts with any success? I hate to waste good cabinets. The speakers still work but at medium to high volumes they are raspy. Is such a procedure possible? I would probably have to drill new holes to fit parts.
