Slim bar.
01 — 2.1 with Subwoofer

Slim bar. Real sub.

The S21 pairs an ultra-slim soundbar with a powerful 5.25″ subwoofer. Dual racetrack drivers deliver 90 dB SPL up top while the dedicated sub handles everything below.

02 — Big bass

45 Hz lows.

Two 9731 racetrack drivers up top and a 5.25″ MDF woofer below, pushed to 180 W peak with <1% distortion. Bass you feel without the boom that muddies it.

03 — Slim profile

42 mm thin.

At just 42 mm tall the bar slips under a TV or across a desk without blocking the screen or stealing the shelf. Big bass, no bulk.

On the stand, or the wall.

Set it on the TV stand or mount it flush to the wall — the keyhole bracket takes the bar either way while the sub sits wherever the bass lands best.
