Description

The GA10-SC64 10" Signature Guitar Speaker - 8-Ohm is an Eminence guitar speaker for musicians, builders, and repair technicians seeking a purposeful replacement or new-cabinet driver. Tones of 1964 still ring true in this vintage voiced 10 inch speaker by amp guru George Alessandro. Very balanced with dynamic character, this ceramic 10 inch speaker offers tight, punchy tone with nice warmth, richness, and sparkling highs. Key specifications include 20 W power handling, 8 Ω nominal impedance, 100 Hz - 5.5 kHz usable frequency range, 98.2 dB sensitivity.

Its construction features a ferrite magnet, a paper cone, a 1", 25 mm voice coil, supporting reliable performance in compatible cabinets and amplifiers. Use it for amplifier upgrades, custom cabinet projects, tonal experimentation, or restoring a working rig with a speaker selected for its musical response. Before installation, confirm the amplifier's impedance requirement, available mounting depth, cabinet cutout, and power compatibility. For best results, choose an enclosure and amplifier pairing appropriate for the published specifications and the desired playing style.
