        Product details

        GRS 8SW-4HE 8" High Excursion Subwoofer 4 Ohm

        • Frequency Response: 30-700Hz

        Frequency Response & Impedance Curve

        the GRS 8SW-4HE has a bass-centric response from 30Hz up to 700Hz 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 an 8-inch driver.

         

        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 8SW-4HE can comfortably handle up to 150 watts RMS of power.
