Bill @ http://www.millersound.net/ repaired the voice coils in a set of 4 1030 woofers for me years ago. I listen to them every day & they are perfect
His cost was very reasonable (less than buying replacements, if I remember correctly).
In the “family” photo, he did my 1030, A70, A60, & HD5 sets.
You can call or email for a quote. Tell him Dan in Chester Springs recommended you.
Best of luck!
