GRS 6LPSW-4 Low Profile Subwoofer

The GRS 6LPSW-4 Low Profile Subwoofer delivers impressive low-frequency performance in a remarkably shallow package, making it an ideal choice for installations where space is at a premium. Designed to produce deep, articulate bass without requiring a large enclosure, this subwoofer is perfect for custom car audio builds, home theatre systems, or any application where a full-sized driver simply will not fit. Its compact dimensions allow it to be mounted in tight spaces such as under seats, in slim cabinets, or within custom enclosures where depth is limited.

Engineered with a 165mm frame and a mere 64mm mounting depth, the 6LPSW-4 fits effortlessly into shallow cavities while still delivering a linear excursion of 4mm and a displacement volume of 415.2 cubic centimetres. The driver’s total Q factor of 1.07, combined with a mechanical Q of 5.26 and an electromagnetic Q of 1.35, ensures controlled, well-damped bass response suited to sealed enclosures. With a sensitivity of 83.2 dB SPL at 1 metre with 2.83V input and a DC resistance of 3.7 ohms, this subwoofer pairs efficiently with modest amplification. The 8-hole mounting pattern and 144.5mm cut-out diameter simplify installation, while the low-profile design maintains a discreet appearance. Whether upgrading a factory system or building a dedicated sound stage, the GRS 6LPSW-4 offers a practical solution for achieving rich, room-filling bass without sacrificing valuable space.
