I'm in need of either repairing or replacing a mid on my 802 series 3 speaker. I bought them used and the dealer here isn't very helpful as i've asked them to get me owners manuals before and they haven't been helpful. Is there a repair kit available or do I just replace the whole driver? For some reason the voice-coil has opened up, the leads are still fine but when measured with a meter it shows an open circuit. What are the prices for repair/replacement?
