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.

You have never had such a compact and capable loudspeaker in your system design toolbox before.

The Theory sb25 is a wide-bandwidth, high-output multi-use loudspeaker, perfect for restaurants, bars, hotels, retail stores, houses of worship and anywhere high-resolution, high-fidelity background or foreground sound is needed.

Capable of astonishing range and output, the 3.8” deep sb25 is literally a jack of all trades and will have you rethinking how you incorporate sound in your next high-value project.

The iw25 fully-enclosed in-wall loudspeaker is the remarkable sb25 model, with a mechanical enclosure to adapt it to in-wall mounting. All of the sb25’s performance attributes remain: robust, wide-bandwidth and dynamic sound with uncanny accuracy and naturalness. The ability of the iw25 to fill large spaces with full-bodied, thrilling sound is shocking. Finally big sound in background and foreground applications does not have ugly, or even visible!

The iw25 in-wall loudspeaker can be operated at low-Z (4-ohms impedance) or by employing its included internal power transformer at hi-Z (70V/100V) at 60W, 30W, 15W and 7.5W.

Like its sister product, the sb25, the iw25 discreet in-wall loudspeaker will have you rethinking how you deploy audio in your premium system designs.

The ic5 in-ceiling loudspeaker is the uber-capable ic6’s smaller brother, offering the same dynamic full-range sound while sacrificing only the last few dB of output.

The ic5’s included compact square and round, frameless perforated grilles disappear into any commercial, retail, corporate or professional environment. 16-ohm and 70V/100V operation.
