I recently refoamed the woofers in my JBL L36. They sound wonderful, until you turn it up. One of the woofers jumps around in and out, while the other is near motionless. The movement is extreme, an half inch or more. It other wise sounds fine, until you turn it up. Did I miss align the cone ? I used a sound generation disc to do the job. Could the speaker have been damaged before I got it from being played without good foam ?
One works great !!!!
Thanks all
