I have an Ashdown mibass 10 speaker cabinet with a single 10" 8ohm speaker supposedly rated 250 watts. I've been using this with an Eden wtx-264 for rehearsal and small club gigs. I especially like the size for gigging with my upright bass. After a couple of outdoor, farmers market dates where I had to turn up the volume too high I seem to have developed a rattle in the speaker. Can anyone suggest a quality replacement/upgrade speaker that would be compatible with this setup?
