B&W CDM1: Poor treble

Forums

Hello,

my pair of CDM1 - bought in 1998, seldom and always played with low levels - has a very weak treble response.
Testing with white noise shows a sharp frequency cut off below 8 kHz, whereas nominal cross-over is 3 kHz.

A German B&W-group manager told me the tweeters' ferrofluid might have become thick so the coils would not be able to swing easily enough.
He told me this would be the result of thermal overload due to too high amplifier output.

As anyone who has talked me me even briefly over the last month knows, I loved reading <I>King Dork</I>. It's a young adult novel that's one-half rant against <I>Catcher In the Rye</I>, one-half spoof of <I>The Da Vinci Code</I>, and one-half Encyclopedia Brown in the 21<SUP>st</SUP> Century. Yeah, I know that adds up to more than one, but that's how good it is. It's also very knowing about rock trivia and absolutely spot-on about what it feels like to be an "uncool" teen.

Filling in (Empty Fox)Holes

Forums

Boy oh boy, how I love the internet. My "Artists House Records" post of a few days ago had me looking through some of LPs and I realized that I had never filled in the hole in my Ornette Coleman collection of his Artists House release "Body Meta". Well a quick search on eBay turned up a few very reasonably priced LP copies with "Buy It Now" prices and I pulled the trigger.
