Just a warning, make sure to test you drivers.
I could not pass this deal up and ordered a pair. They got here today and I pulled them out to have a look. The foam gasket on the front of one of woofers had come loose in a couple spots, due to shipping I'm sure. That was an easy fix.
I started doing some free air testing to check for noise and such. First thing I noticed is that the tinsel leads seem to slap the back of the cone before reaching xmax. I pushed those off to the sides and down some which fixed that problem. Anyway I turn it up a little more (have it set on a 15hz sinewave) and I start to hear a soft clanking noise, hmm. I know I can't be at the mechanical limits yet, the cone only looks to be doing at most 1" peak to peak. If I turn it up the clanking gets louder. I switch over to the other driver and can push it much harder up closer to 2" peak to peak without any bad noises at all. I know something is wrong with the driver, I play around with it a little more and finally found the problem:
Looks like about 1/3 of it has cracked and come loose. Nice to find on a brand spanking new driver
So who's got an idea on what to use to glue that back down? I am thinking JB Weld but am open to other suggestions.
