Replacing dead woofer on ProAc Tablette Sig 50 (NYC area)?

I have a pair of ProAc Tablette Signature 50s; one of the woofers is dead. I brought it to a local guy in NYC, who seems knowledgeable but is apparently not some famous high-end guru; he says that the woofer needs to be replaced, but he doesn't have access to one that will fit.

I've messaged ProAc, who haven't replied in a few days, and I'm just trying to get a sense of what my options are. I've always liked these speakers, and I would like them to work, but if it's going to be a years-long effort of finding the right person somewhere in the world to fix these, I'll just have to toss them and find another pair of something. 

Is finding a replacement woofer easier than this guy thinks? Or is there somewhere I should be taking them to in the NYC area who'd be able to fix this? Obviously, I am myself extremely unsavvy, technically, but I'd hope that these are both repairable and worth repairing.




If you want to send my the good driver, I'll run full curves and specs and then help you find a proper replacement. I am in the St. Louis area. 

one idea not mentioned is Millersound who repairs drivers, in PA

ProAc not listed, but SEAS is.

your driver is

unique face frame and rear basket (you have)

unique bullet (you have)

cone (is your cone good?

voice coil (perhaps blown). IF it is the voice coil, perhaps SEAS used same size voice coil in other drivers, i.e. Millersound might have the voice coil.

btw: to prove it is not the crossover: have you tried temporarily moving the good driver to the bad woofer's location?


Seas did indeed use the same woofer. I have used them a few times. The Proac driver is an MP14 series, they customized that series with a phase plug for Proac. I have only seen the phase plug version made for Proac. Look at an MP14RC (H0688) or MP14RCY. These were both listed as Midbass drivers

Well, I hadn't originally contacted Millersound because their website strongly discourages you from getting in touch about brands that are not listed, but, as pointed out above, they do list SEAS. So I emailed, and they in fact think that they would be able to repair these.

I'll have to figure out how to remove the woofers, which scares the hell out of me, but I'd be thrilled if I could in fact get the whole thing working again.

I confess to being exhausted by this project, but....

Will update. Thanks for the suggestions!
