I have slammed the Hell outa their soft parts only issue was the spider spacers started to go which caused the spiders to also fail. Wasn't too bad, much better then the stock soundstream xxx parts lol which blew to Hell off little power. The T3 recone has seen 6k+ on music without a problem. I personally had good luck with the tsns recones.they tried shinning a turd to make it like gold..yeah they had a few good subs, but the majority were just meh.
motors were good, but the soft parts were like tissue paper and printer paper.
