Hi there.

At first I would like to excuse my bad English.

I am new to this forum, but I have had several martin logan speakers.

Prodigy 2 times
Ascent I 1 time
Ascent 1 time
Cls II 1 time

Now CLS2Z.

I bought my CLS2Z second hand from a shop 3 weeks ago.

I have 2 pairs of speakers , Audio Physic Avanti 5 + my CLS 2Z.

I played loud music for the first time yesterday , I am using a ML Grotto subwoofer.

I noticed from 1 of the panels a vibrating noise, the folio banging to the frame.

I played loud but not to loud.

When i look at the panel vibrating I can see 2 small wrinkles on the folio , one is 3 cm. long and the other 5 cm.

I can see the panels are from november 2012 but they were replaced march 2015 according to the invoice.

The question is : Did I buy some bad speakers with 1 broke panel? or is there something to do about it?

I was told the speakers were in mint condition with 3 year old panels.

They sound amazing and I really thought they should be my last speakers.

I really look forward to hear some of You experienced Martin logan Guys if You have any advise here.

Thnk You very much indeed.
