Digging deeper, the new 12" 600 watt Twister SQ sub contains a T-shaped top plate that widens the motor’s magnetic field, significantly increasing upper bass response. Its wide poly/cotton spider handles high excursions flawlessly, thanks to the increased diameter and a unique shape. The sub’s improved voice coil now rates to 220 incinerating degrees Celsius, which keeps your bass raging longer than ever. And with a new stamped-steel basket, rugged magnet boot, and super-grip front gasket, the SQ sub gives any woofer in the neighborhood a run for its money.
