Repair service for Revel B15 subwoofer


I have an old B 15 subwoofer that I use as a center channel bass source with my home theater system which is otherwise very modest.

Does anyone know a service or a shop that has some expertise in repairing the electronic components of this unit? Thanks for any response.

I've seen repaired units available on George Meyer AV, I would try calling them and seeing if they can help.
