PROFICIENT LSB3 3 Channel Passive Soundbar


By combining front left, center and right speakers into a single, sleek soundbar, the LSB3 is the easiest way to make multichannel surround-sound exciting to the ear and beautiful to the eye.

The LSB3’s six woofers – two for each channel – use the same ultra-light, ultra-stiff graphite composite cones used throughout the Protege Cabinet Series, and its three tweeters use the same sweet-sounding silk domes.

Use this three-channel Passive Soundbar with any A/V receiver to build a compact yet powerful home theater system.
The LSB3 has a matte black finish and removable black grille with neo-magnets.
Includes a Proficient-designed horizontally adjustable wall-mounting bracket.
