Refurbishing Avalon Ascent Mk 2


After 25 years of service my Avalon Ascent Mk 2 have started to distort especially with classical piano.  I have isolated the problem to both 2" aluminium-manganese mid drivers.  These, I believe, were built by MB Quart of Germany, now out of business and the part seems unavailable.

I would greatly appreciate any suggestions on how I could bring back these speakers to their former glory. Thanks.

Hi franzshubert,

Try placing very small pieces of Dynamat on the dustcap of the offending drivers. It may take several attempts to find the right spot but this may work. Worth a try.

Erik has a great point.  I assumed that was done and no remedy was available.
Normally, the dome in the center of the driver that protects the voice coil from dust and such.  I just looked at pic of your speakers and see that it has a large single dome like the mids in my Thiel CS5i's. In that case, try different locations on the dome. Be VERY careful, let the adhesive properties of the Dynamat backing do the work of holding it in place, do not press lest you dent the dome. Just lightly touch it to the dome material.
Franz,

If Charles doesn't pan out, I second djohnson54's recommendation to contact Miller Sound. Excellent on refurbishing drivers.
