You have never experienced bass as “musical” as the Theory SR subwoofers.

Built-to-order in the U.S., SR Series subwoofers provide powerful bass output that is visceral and exciting, but also shockingly tight and tuneful. Folks familiar with Theory’s smaller subwoofer transparent and textural sound, will immediately recognize the quality of the low frequency reproduction.

The SR-212LF, the smallest of Theory’s SR Series subwoofers, houses two proprietary 12” 1,400W woofers with 4” voice coils in an surprisingly compact and easy to transport package.

Like all SR subwoofers, the SR-212LF features 20mm “top hats” on three surfaces for full range speaker pole mounting, driver access for field service, ergonomic handles, and anti-skid rubber feet that mount to M10 fly points.

Passive versions can be upgraded to powered versions with a Theory SR Series amplifier kit (sold separately).

Optional accessories include the Theory SplitYoke­™ Multipurpose Mounting Brackets used to install the SR-212LF easily vertically or horizontally on the wall, ceiling, and other surfaces.

The SR-212LF subwoofer is available in black and white, and in passive or active versions depending on the installation need. Upgrades include custom paint matching and weatherizing (of the passive version only).

Capable of astonishing output combined with high-fidelity sound, the compact SR-212LF will have you rethinking how you design your next portable or installed sound reinforcement project.
