I like the older type-r's better, about 6 months in with 1200 watts to one in a ported enclosure, the front of the sub started blowing chips of plastic off the dustcap. I called to try and get an RMA they said theirs no way that could happen without someone puncturing it but it sit in my trunk without anything even close to touching it, so now I have a barely used type-r wasting away in my house. I guess I'll have to recone it myself if that's possible.
Get the older type-r the gray dustcap looks better anyway, imo.
