Reaching out to the gods for ideas. Upon rebuilding these D9s I discovered poor woofer performance with some rubbing, garbled distortion and unusual excursion. I opted to replace the voice coils and spiders. On the bench with direct connect to amp the freeair results sounded good. But installed back in the cabinets I still get the garbled distortion at high volume. Woofer movement is now perfect and smooth and the sound is good but still distorts at high volume. Running gear is plentiful in the power department and performs flawlessly on every other speaker I have built in the last few years. My guess is crossover. I replaced the elctrolytics with PE caps like usual but the only unusal thing I did was parallel gang multiples to achieve the original values. The woofer circuit has 40uF between power and ground after the inductor. I parallelled a 22u,F17uF and 1uF to get 40uF. Im thinking this is the culpret or possibly the inductor. Ive never ganged caps before and coincidentally never had an issue before... Any ideas anyone?
