15″ Platform 2 Subwoofer

I’ve had my platform 2 15 for a few years now but on the inside of the cone it’s dated 2013 it’s five years old it’s old enough to be in kindergarten lol I bought it used and it has been my daily and I’m hard on it for sure slamming it full tilt in a probably 4³ foot box with a pretty nice size port on it not really sure the dimensions and it just takes it psi quality goes un matched anybody who knows anything will tell you this
