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.


OP here, finally following up on this. I've spent a lot of time talking to people, all of whom were very nice and generous with their time, but I seem to be at a dead end.

ProAc confirmed that the original woofer was the SEAS HO803-08, but that they don't have any spare parts for this. I've spoken with new and old SEAS dealers who also don't have a replacement (indeed, though ProAc was very specific about the model number, I can't find any evidence for it anywhere).

I spoke with the Sound Organization, the US distributor, who also don't have any replacements. They said that simply dropping in a similar-size woofer would be a bad idea, due to issues with how specifically the originals were designed. They recommended a few different repair or re-coning shops, none of whom were able to help. Madisound were unable to help, and I spoke with a few dealers (including the NJ and the Toronto ones) who also didn't have any ideas.

I think I've done all I can do, and as this particular line of inquiry is unpleasantly stressful for me, I think it's time to throw in the towel. I'd welcome advice about how to get rid of these—perhaps someone is more patient than I am, or needs just one perfect speaker, or needs parts.... Getting some money would be nice, or I could just give them away.

Thanks for sticking with this!



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
