B&W and deteriorating Kevlar drivers

Not me as they're rather expensive for me. and I also don't have the space for them. I have owned the 602's and currently own the CM7's. My 602's held up well and I sold them to a lucky Agoner after 12 years of enjoyment. I didn't notice any issues with my kevlar drivers on the 602's but that doesn't mean it wasn't there. Maybe that's why I sold them. I'm sure if it happens with the mid drivers, it can happen with all the kevlar drivers in their lineup.

Just curious where you live. Could it be the climate and the humidity (or lack thereof) that is a contributing factor in this? Just wondering.

Angst0,
Are your speakers exposed to sunlight from a window or skylight? It could be that the Kevlar broke down 'chemically' due to exposure...just a WAG.
Kevlar does have a 'honk' as some critics have described it.
It was used for it's great strength to weight ratio...personally, I do hear the coloration somewhat.
In the THIEL CS5, Jim's best work (I haven't spent time with the 3.7 which gets raves) he used a Kevlar midrange, but I didn't hear the same coloration. Of course he was using it across wide bandwidth, at 6db per octave it would have seemed to show any weakness in the frequency extremes, EXCEPT for the fact that there were so many drivers, 1 Tweet, 1 Dome, 1Kevlar, and then three paper woofs,(or composite, damn I'm so old I forget things like this too easily). They may have been a plastic coated, paper, OR maybe a poly.

Again, didn't hear that 'honk'.

BTW, the sunlight thing...is that a possibility?

Thanks for the comment. The speakers are in a sunny room, but not in direct sunlight. You can see pictures of the room and system in virtual systems. http://forum.audiogon.com/cgi-bin/fr.pl?vevol&1262106902&view Humidity not unusual....Phila area.
