Description

The LEGEND BP 102-4 10" Bass Guitar Speaker is an Eminence bass guitar speaker for musicians, builders, and repair technicians seeking a purposeful replacement or new-cabinet driver. Recommended for professional bass guitar applications in a sealed or vented enclosure. Works well in single or multi driver designs. Key specifications include 200 W power handling, 4 Ω nominal impedance, 40 Hz - 2 kHz usable frequency range, 90.5 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.
