Platinum Series L12-40A

The Platinum Series L12-40A is an Eminence guitar speaker for musicians, builders, and repair technicians seeking a purposeful replacement or new-cabinet driver. The Eminence Platinum Series L12-40A is the Alnico-voiced heart of the Platinum lineup—a 12-inch, 40-watt guitar speaker designed to capture the warmth, chime, and musical compression that made the most legendary vintage amps iconic. Built with a premium Alnico magnet, the L12-40A responds dynamically to your picking hand, delivering harmonically rich cleans, smooth breakup, and expressive overdrive that sings. Key specifications include 40 W power handling, 8 Ω nominal impedance, 80 Hz - 5.2 kHz usable frequency range, 97.3 dB sensitivity.

Its construction features a alnico magnet, 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.
