GS8ND2 SHALLOW WOOFER / SUBWOOFER

1/3

Overview

​

The GS8ND2 is designed as a small and shallow subwoofer to be used in a sealed enclosure as small as 0.25 cubic feet or a vented enclosure as small as 0.5 cubic feet - perfect for under-seat boxes in trucks. It can also be used as a replacement for many factory-installed 8” subwoofers in enclosures or mounted in an infinite baffle.

​

For cars in which no additional subwoofer will be used and in which the factory location in the front doors is a 6×9” or an 8”, the GS8ND2 is a great solution.

​

The GS8ND2 features a shallow fiberglass cone and a compact but powerful neodymium magnet, dual 2-ohm voice coils, a Nitrile Butadiene rubber surround and a flat Nomex™ spider. With a mounting depth of just over 3”, the GS8ND2 fits many applications that a standard 8” woofer doesn’t.
