BST BMT315 – 3-Way Active Speaker 15″/38 cm 800 W RMS Tri-Amplification Class D with DSP

The BST BMT315 active loudspeaker combines power, precision, and versatility for stage, bar, concert, and club applications.

The built-in DSP offers three presets (FLAT, LIVE, DJ) to tailor the sound profile to the environment, while controls and signal and limiter LEDs make live setup easy. With two line XLR inputs and two outputs, a 120Hz or full-range hi-pass filter, and a multi-ply wood enclosure with a textured black finish, the BMT315 is ready to integrate into any professional system.
