I wouldn't reccommend that!

My mid dome's on my old speakers died without excess volume*. Those dome's are a touch delicate in reality. I know a guy, Kevin, who's been through three pairs and some over on audio circle forum have had the same fate. I wonder if the ATC's have the same weak point? - as they used to have the exact same midrange unit years ago. Odd, as the rest of the components are rock solid.

* I did sample very excess volume AFTER I got the replacements - just to check!
