Wilson Audio Sophia Series 2 midrange buzzing

[sfseay]

I just bought a pair of used Wilson Sophia Series 2 speakers. I drove quite a distance to get them and paid a fair price. When I got them home and connected them I noticed one of the speakers has a midrange cone that is faintly buzzing/rattling even at low volumes. I didn't notice this when I did my test listen at the sellers house prior to bringing them home. It is pretty noticeable and I have eliminated the preamp, amplifier, and speaker wire as the cause of the problem.

In doing some research it seems the midrange driver is a ScanSpeak Revelator 7". My question is does anyone know if Wilson tweaked these speakers or do you know if Wilson used the stock midrange speaker from ScanSpeak?

I have reached out to the seller and hope he will make this right, and I will call Wilson and get a price on a replacement midrange speaker. I found a site that sells the ScanSpeak Revelator 7" for under $220.00. I can only hope the ScanSpeak Revelator 7" is a direct replacement. They look identical, but Wilson is known for adding their own twist to speaker components.

Thanks in advance for any help!

Dunno. You might try contacting Wilson. I thought their support was supposed to be pretty great. They might have parts available though they may or may not charge a premium. I might not go out of my way to mention that I bought them used.

Good luck. Absolutely great speakers!

I have had something similar happen a long time ago to a speaker. I remembered gently pushing the speaker cone and hearing something like a scraping noise. I tried that with the Sophia midrange last night and heard the same thing.

I believe it is an indication of a bad voice coil.

I had a pair of Monitor Audio speakers that I bought new. After about 15 years one of the mid-woofers did the same thing, buzzing low volumes and scrapping when I pushed the cone. It was the voice coil and I foolishly chose to sell them instead of replacing the failing driver. Good luck with the seller and with Wilson.
