Default Diamond Coax subs blew up

Hey folks. I have a set of the Diamond coax subs in my bags and both of them had the capacitor blow up and the spider separated from the woofer. They were crossed at 80hz 12 db slope and the levels were set with a DD1+ with no over lap. Any ideas what caused this? Oddly enough the woofers still play.

by the way I have hated these from day one and I am waiting for a set of Hertz Hertz NEO 690 to arrive. Been on order for a month and a half

Are they still under warranty? Get them replaced, then sell the new ones and grab something else.

My new Hertz NEO 6x9 just showed up. They sound way better than Diamonds did. I have been trying to contact Diamond for a warranty replacement but I haven’t had any luck yet. If they do get replaced I won’t put them back in anything. Huge advantage to the NEO is how small and light they are as well.

Did you buy them direct through diamond? or a rep?

the old MPX 690.3 Mille Pro's the Diamonds are a bit brighter and a bit more bass. better for the lids while riding IMO. I haven't tried the new Hertz ones, their less weight and size would be a big plus.
