DESC: The Pioneer TS-SW3001S4 is a Shallow mount 12“car subwoofer with 400 watts RMS and 1500 watt peak output designed for optimal performance in sealed enclosures. With the Basalt fiber technology incorporated in it, you get low, well defined bass. The Pioneer TS-SW3001S4 is designed using Air Suspension Control System that locks air between the main and drive cone to reproduce exceptionally clear, low distortion bass sound and it also eliminates traditional spider structure thus reducing the depth of the sub. Thanks to its 3-Layer fiber woven radial woofer surround, you get natural sounding resonant bass. No doubt, you can hide the Pioneer TS-SW3001S4 car subwoofer at tight, hidden places with its shallow mount design, but its booming bass will always make its presence felt.
