The RSRMO-8 Replacement Woofer from GRS is a precision-engineered 15-inch driver designed to restore the authoritative low-end performance of your Realistic Mach One speakers. As a direct drop-in replacement, it offers a straightforward solution for reviving classic loudspeakers that have lost their original bass response, ensuring your vintage system continues to deliver the rich, room-filling sound it was renowned for.

Technically, the woofer features a paper cone for natural, articulate sound, with a 2.5mm Xmax ensuring linear excursion for precise bass. The 8-ohm impedance and 7.2-ohm DC resistance pair well with standard amplifiers, while a total Q (Qts) of 0.56 balances transient response and extension. The 90dB sensitivity (1m/2.83V) ensures efficient power handling, and the 349.3mm cutout diameter with six mounting holes simplifies installation. A copper voice coil and 1.82mH inductance contribute to controlled, distortion-free performance.
