spl levels, freq. response, space, and the amount of power the she can handle.

none so far

This is one of the best 12's i have ever owned. the freq. response is amazing. It's a 10, 12, and 15 all in one. I have a hatchback with an 800 watt sony explode amp. I bridged my amp and wired the dual voice coil in, hooker her up and boom. The spl level are incredible for only one 12.
