The versatile 8SW-4HE 8" high excursion subwoofer from GRS is designed to produce excellent low frequency extension in a variety of designs. Suitable for both sealed and vented enclosures， this driver the ideal replacement or upgrade for your existing subwoofers with worn out or blown drivers. Featuring extensive venting， rubber surround， high temperature voice coil， low Fs， and 10.5 mm of excursion the 8SW-4HE is built for remarkable bass response on a budget.
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.
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.
