Outstanding performance for a 4" midrange. The motor is somewhere between the Revelator and the Illuminator. The application is a bit tough to swallow, basically 1 cubic foot and loads of power but as long as you have that you can achieve a ridiculously low crossover point with this guy and get decent output. At SB acoustics prices this is a bargain top notch performance driver for those that have lots of room to play with. Should work really well in IB too.

These scream BMW to me. IE no midbass to share the door volume with, low crossover point to help the under seat midbass out, and good output to match. Oh and lets not forget the 4" IB center channel.
