Great forum, glad I discovered it.
I have a pair of 4301B Control Monitors which I bought brand new a long time ago. One of the woofers went bad years and years ago and I went out looking for a replacement.
Not knowing any better, I purchased a non-JBL woofer as a replacement.
It works fine, but after reading this forum, it bothers me that it's not original JBL. Where can I get the correct woofer to replace the the alien one?
