Description

The LEGEND BP 122 12" Bass Guitar Speaker is an Eminence bass guitar speaker for musicians, builders, and repair technicians seeking a purposeful replacement or new-cabinet driver. A 12" bass guitar driver that delivers warm, rich tone and deep bass. A big brother to the popular 10" Legend BP102, this 250 watt driver is at home in small sealed enclosures, and also works well in Pro Audio and Home Hi-Fi applications. Key specifications include 250 W power handling, 8 Ω nominal impedance, 35 Hz - 2.3 kHz usable frequency range, 94.1 dB sensitivity.

Its construction features a ferrite magnet, a paper cone, a 2", 50 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.
