Orion subwoofer repair

Question

I have an orion hcca 10d.2 subwoofer, and one of the sets of two ohm voice coils seems to be blown. I am trying to find someone who can fix his sub with the quality parts it was originally built with. The sub looks brand new, and has very little play time on it. Orion wont repair it, and the service department didnt recomend anyone.
