Eminence GA-SC-X 12" 60 Watt Signature Neodymium Guitar Speaker

Overview

The Eminence GA-SC-X 12" Signature Guitar Speaker is designed to blend the classic tones of the 1950s and 60s with a modern edge and efficiency. Developed in collaboration with George Alessandro, this speaker utilizes a lightweight neodymium magnet, a material not available in the golden era of guitar speakers, while maintaining the warmth and richness of traditional speaker construction.

With a tight and punchy low end, warm midrange, and a moderate high-end response, the GA-SC-X is versatile enough for rock, blues, and country genres. Its higher power handling (60W) and increased efficiency make it an excellent choice for gigging musicians and studio players alike. Whether used in open or closed-back 1x12, 2x12, or 4x12 configurations, this speaker delivers articulate and responsive tone with medium break-up modes, ideal for both lead and rhythm guitar applications.
