[QUOTE="Papermaker85, post: 8508853, member: 572595"] So I put around 4kw with a clip to test it limits.after playing it hard I heard a slight scratching sound. So I cut it up to see what was up! The coil held up fine but the former bubbled and was causing it to rub on the t-yoke. I'm relieved honestly because I thought the coil was weak. Needless to say it's a really easy fix. Going to double the thickness of the former. Not only will it stop it from failure it's going to increase the thermal power handling beyond what I expected with the thicker former and added cooling I implemented. Originally I figured around 2500 to 3k, Now I'm sure it will handle 3500 clean easily. Note the driver didn't really fail it still pounced and it made no noise when it was playing. I just wanted to re-cone it with a vented former and spaced and mirrored spiders to improve the linearity and cooling cuz I'm an[B]al[/B]..
