I bought some recone from them, and from PAP for SS XXX subs (15" and 18"). They deliver fast, for sure, but I can't say their products are the best of the world, like I've heared ! some of my friends don't want to use them at all, now. But those friends are not really taking care of their equipments, so I can't really judge. I needed a recone kit for a DD sub recently, I did not try any of those PAP or PSI. I contacted DD directly and made the deal from an official dealer. DD put me in contact witht the nearest dealer. If I had to buy a recone for a Fi or an SSA sub, I would always get a manufacturer recone first. I'm currently waiting for a Fi btl N2 rcone and basket : original from Fi. Nothing else !
