The woofers on my Aerial center channel speaker have burned coils. They are 7" 16 ohm speakers. No one seems to have the parts to repair them. The manufacturer wants $175 each for these speakers. I have great digital photos of them. Does anyone know where I can buy them cheaper or maybe have them repaired. The Aerial center channel speaker was $1500 when I bought it. I am sure it is close to $1800 today. Thanks for your help.
