Overview

S115V-LF-8 Replacement 15" Woofer for Yamaha Club Series S115V Speakers GRS

S115V-LF-8 Replacement 15" Woofer for Yamaha Club Series S115V Speakers

Don't just replace - upgrade. Bring those old and worn-down Yamaha S115V Club Series speakers back to life with the GRS S115V-LF woofer. Designed to be an improvement of the original, these can be swapped in only a few minutes with a few basic tools.

The GRS S115V replacement woofer has been designed to improve the performance of your Yamaha Club Series speakers by optimizing crossover summation of the original installed woofers. When the GRS S115V-LF-8 is paired with the GRS S115V-HF-16 compression driver, you can expect an improvement in off-axis response, perfect summing at the crossover point, and increased detail and clarity in the high-end providing performance where you expect it most.

Improved Performance

This woofer shares all of the important design features of the original, such as a 3" edge-wound voice coil wound on a Kapton former and an engineered cone profile for ultra smooth upper midrange response that bests the original. When installed in the original cabinet, the bass extension of the GRS S115V is preserved, showing the same LF performance as the original, but with increased intelligibility that you would expect from a PA speaker thanks to its ability to fill in the notch at 1800Hz.

A solid cast frame and large ferrite motor structure bring everything together, allowing this woofer to hold up to the harshest environments of live audio. Combine all of these traits together and you get not only a great, inexpensive replacement, but a solid improvement over the original - all while maintaining the strength and durability that allows it to last for years to come.
