Refurbishing Avalon Ascent Mk 2

I have the exact same problem. It’s significant on the left speaker and subtle on the right speaker. But the distortion is definitely coming from the mid range driver. I did disassemble the mid range driver that is severely distorted and found no deterioration at all in the Dome. I reassembled and it did not improve.

I have also attempted on multiple occasions to contact Avalon both by phone and through their help email system. It’s been weeks and I’ve had no response whatsoever, other than an automated response immediately after sending the first email.

I have carefully eliminated other potential problem areas such as preamplifier, amplifier, and crossover networks. All my gear is Mark Levinson.  Distortion persisted independent of audio source.

It's really disgraceful and angering that a company like Avalon chooses to ignore previous customers who have issues like this. It should be a real warning to potential new customers. 

Several years ago, i had an issue with my Isis speakers where I needed to buy a new set of diamond tweeters. What they wanted to charge me was totally out of control and asked that I send the speakers back to Colorado and charge me $5600 just for the analysis. I sold the speakers and said I would never have anything to do with Avalon, and still to this day feel the same. My feeling is that their interests are only in Asia.

I had Avalon many years ago my dealer upgraded them in my home.I guess now there history as far as prices and customer service used to be a great company.
