B&C 12SW115 12" LF Driver 4Ω Subwoofer 3400W Professional Audio Woofer System
Compact horn subwoofers designs stuff the motor into a sealed chamber where it bakes in its own heat. The 12SW115's 115mm (4.5 in) split-coil design is the antidote. 3400 Watts of power, an aluminum demodulating ring plus our split voice coil for low Bl and Le distortion, and 13.5mm of Xmax. Not subtle, but maybe exactly what you need.
