    GRS 12SW-4HE 12" Paper Cone Rubber Surround High Excursion Subwoofer 4 Ohm

     

    Engineered for extended low frequency response and flexibility, the 12SW-4HE 12” high excursion subwoofer from GRS is an ideal replacement driver for existing subwoofer systems or an excellent choice for new economical designs. Capable of producing powerful bass response in both sealed and vented designs, the 12SW-4HE is suitable as a drop-in replacement for most existing 12” subwoofers. The rigid paper cone is supported by a large diameter spider and rubber surround to keep excursion linear while providing reliable performance. An extended frame and bumped back plate allow ample mechanical clearance to avoid damage when driven to high excursion. With a high temperature 2” voice coil wound on a thick aluminum former the 12SW-4HE can comfortably handle up to 250 watts RMS of power. Extensive venting through the frame, pole piece, and magnetic gap dissipates excess heat to keep power compression to a minimum, even when driven hard for long periods. Capable of incredible low frequency extension, the GRS 12SW-4HE is the perfect driver for true bass on a budget.
