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

Thanks for the suggestions. I worry that using something like a Rhythmik would create time alignment issues and I’m not sure at what frequency the bass module becomes audibly directional. I had used 2 subs with them set to 170hz and a 12 db slope. The SUB225’s were set to 170hz if I remember correctly. I like my subs to add meat to the music not slam me.

Knowing that Avantgarde would probably charge a ton for a repair, I'd look into a plate amp replacement.

Isn’t Bob @ Rhapsody in NY a dealer?  I know he was and should have some info even if he dropped the line.

Fixing 4 amplifiers may be costly and the 225 was one of the reasons I sold my Duos it never sounded as a whole. Maybe consider having a pair of bass horns built. I used bass horns with my Duos they became a far more enjoyable loudspeaker.
