About The Theory Audio Design sub12 Passive Subwoofer
Today's high-resolution immersive audio soundtracks are bigger and more dynamic than ever before. Likewise, in high-end commercial environments, powerful, low-frequency audio reproduction is essential. To reproduce the weight and scale of today's content, Theory offers two passive in-room subwoofers with 12" and 15" woofers respectively.
The sub12 passive in-room subwoofer employs a high-power, 1,000W, 3” voice-coil, long-throw 12” driver. With a maximum output of 122dB the bass the sub12 provides belies intuition, extending deeper than seems possible, with tight, tuneful expression. The sub12 offers the highest output available in its class.
From the outside, Theory subs exude high-quality. There is no need to hide them in the corners of the room or under a table (though you can). Like a high-end piece of furniture, Theory subwoofer cabinets are crafted from solid HDF with beautifully curved edges, and a high-gloss black finish.
The audio performance provided by Theory subwoofers is the only thing that trumps their aesthetics. Hyper detailed with extremely nuanced texture, Theory subs deliver low notes with a level of authority you can feel in your gut. The sub12 is the perfect in-room subwoofer complement to Theory's full range speakers to create a truly astonishing high-energy environment. The performance and versatility of the sub12 must be experienced to be believed.
The Theory of Everything: Theory is genuinely unique - their products have completely changed the level of performance attainable from small to medium size installed sound systems. Part of the way they attain this level of performance is by employing proprietary DSP techniques to process the signal for their loudspeakers and subwoofers with a very high degree of precision.
As such, the Theory ecosystem of products is a little different than what you're used to as all Theory loudspeaker models require the application of Theory High Resolution Digital Loudspeaker Processing. For this reason, it is best to think of Theory loudspeakers as "active" or "powered" speakers - Theory have just elected to place the electronics, normally installed inside the loudspeaker itself, in rack-mountable chasses, outside the harsh environment of the loudspeaker, and where wiring and service of the electronics can be accomplished painlessly.
So, when configuring system designs, always pair your chosen Theory loudspeakers with appropriate Theory Amplified Loudspeaker Controllers. These highly powerful and flexible units will make deploying Theory systems simple and painless and will guaranty the best performance available for your application.
