Frequency Response & Impedance Curve
the GRS 12SW-4HE has a bass-centric response from 26Hz up to 500Hz and is highly efficient within its passband. This efficiency and a low QTS lends itself well to both vented and sealed subwoofers for incredibly deep bass from a 12-inch driver.
Bass-worthy construction
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. The rigid paper cone is supported by a large diameter spider and rubber surround to keep excursion linear while providing reliable performance. 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.
