Refurbishing Avalon Ascent Mk 2

Yes I have tried multiple amps, preamps, DACs and cables.  The distortion remains.  It is only ameliorated when I disconnect the midrange drivers .... hence my conclusion that they are at fault.

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.

Dave,
When you say "dust caps" are you referring to the cloth grill or the wire mesh protecting the drivers?

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.

Hi Franz...

So the first obvious question is, have you reached out to Avalon? They may have replacements for you in stock.

Next, I don't hear about midranges going out very often. Double check to make sure it's not a crossover thing. Examine the crossover for two possible items:

1 - Burnt resistors
2 - Electrolytic caps (anywhere).

Replace either.

Best,

Erik
