Avantegarde Duo repair.

Thanks in advance for any help. I have a beautiful pair of automotive blue AG Duo’s (not the 18ohm version) and both my SUB225’s have failed. I actually have 4 SUB225’s.  One still works fine, one blows a fuse immediately and the pair that were in use are not powering up but the fuses are fine.  Happened last week. 
 

I live in the Chicago NW suburbs. Any recommendations for a quality shop to diagnose and repair?

Additionally does anyone have an opinion on value as is for someone with the knowledge to repair?

 

Thanks,

 

Jon

Yes, I built a good num of bass horns for Trio owners and a pair for my Duos.

Located S WI if you want to hear a bass horn. Not trying to sell just trying to help.

Jon,  Thanks for posting.  I have 225s with my  AG Trios and really like them.  All are still working fine (fingers crossed).  The thing I like about the 225s is both volume and cross-over point can be set to match room acoustics.  That is a big plus over other subs.

Please post F/U if you find reliable repair source.

Good to hear John Ks comment.  Would definitely be interested in a horn sub at some point.

most-likely amp output stage is blown and needs to be replaced.

local techs can do that for around $300 and it seems to be generic job
