Ok, I have a pair of D9s gathering dust in my garage. Wishing there was a 15" replacement that had that iconic red ring but was not prone to rot. Like made of rubber. Loved the sound back in the day. Still have my amp but display is gone. My Yamaha RXV1050 .so it just sits. Using Pioneer VSX452 sometimes with some Bose speakers. However most of my listening is with earbuds. WHOOPS, A little off topic. Is it worth to fis my CV 15 inch woofers? Replace them or swap ror sub woofers? I really loved those speakers, cant seem to part with them.So what is the answer?
