        Product details

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

        The GRS 8SW-4HE 8” 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 8SW-4HE is suitable as a drop-in replacement for most existing 8” subwoofers.

         

        Key Specs:

        • Nominal Diameter: 8"
        • Power Handling (RMS): 150W
        • Power Handling (MAX): 300W
        • Impedance: 4 Ω
        • Frequency Response: 30-700Hz
        • Sensitivity: 85dB 2.83V/1m
        • Voice Coil Diameter: 2"
        • Maximum Linear Excursion: 10.8mm

         

        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.
