Duntech repairs?

Thanks. Pryso, I completely agree. I pulled the drivers which appear to be the same except that one looks much older and possibly was not reconed (assuming the other three were) or was possibly a "used" replacement. The cone fabric and foam is different and the dust cap is smoother and less spherical than the others. There are no markings on the driver that I found other than a sticker (covering another identical sticker) which read "M21WN-09 08OHM711B". The sticker on the apparantly newer speaker read "M21WN-18 08OHM807". Can anyone decipher this?

I would send a note to both Madisound (since they previously sold Dynaudio) and Dynaudio, asking about the model numbers. The similarity of the numbers suggests they are all the same manufacturer.

If all else fails, you might contact Millersound, explain the situation, ask if he will evaluate all four woofers, and then rebuild as necessary to make two matched pairs.

This may all seem like a great deal of trouble but I suspect you will find it worthwhile once you have your speakers performing up to spec.

Apart from Millersound being able to repair the woofers, I know that Bill is a huge fan of Duntechs.

Since we've never talked about it beyond him consistently the speakers me, I'm not sure how deep and intimate his knowledge of the products are in reality. My guess would be he possesses it.

For the record the Duntech Marquis had Vifa Drivers. I had the original drivers and they were Vifa with the original foam surround that started deteriorating. I contacted Duntech and they sent replacement Vifa Drivers. This was some years ago and I believe they no longer have a supply of the replacements. The replacements were same paper cone material and size and specs but the casting on the baskets were substantially improved and the surrounds were rubber. It was huge improvement, but a lot of it probably came from the fact that the surrounds were rotting out on the old speakers. The bigger cousins from what I understand are Dynaudio.

send the woofers to Bill LeGall at Millersound in Pensylvenia actually send him all the drivers and he will work some magic on those things that you can't even imagine
