Re: [TCML] I think I ruined my 6" secondary.

Hey David...

As far as long term durability...  the exterior is great, boding issues 
with the insulation of the wire over time is the problem ( but then 
again maybe the form being heavy walled shipping tube and somewhat 
"flexible" could be part of the equasion)  Never had any problem with 
cracking or spiderwebbing but if one tried hard enuf they could probably 
get it to happen with Berh 50 after it has aged in the workshop for 
several years....
