GS Series

GS8ND2 Audiofrog Lautsprecher

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.
