About The Theory Audio Design sb25 On-Wall Speaker
The sb25 on-wall and pole mount multi-use loudspeaker is the "Swiss army knife" of installed loudspeakers with compact dimensions and jaw-dropping sonic performance. Its inert aluminium construction and tuned ports provide surprising low frequency performance with extended response and surprising dynamics. The sb25 offers the widest bandwidth and highest output available in its class.
The extruded aluminium construction allows the sb25 to achieve true full-range performance and high-output in a package that is only 96.5mm deep (100mm wall mounted including brackets). No other product of equal depth can come close to its performance.
With available optional Universal Mount Adapter, the sb25 can go almost anywhere and look sleek and unobtrusive doing it. Its slender enclosure, clean fabric grille, premium finish and gentle sculpted curves allow it to "disappear" into the architectural background but look surprisingly handsome in environments where it's easily seen - stealth and pretty at the same time. The performance and versatility of the sb25 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.

Our Review
The Theory Audio Design sb25 is a bit of a shape-shifter - in the best possible way. Dubbed the “Swiss army knife” of installed loudspeakers, this sleek on-wall (or pole-mounted) speaker punches well above its weight with rich, dynamic sound and low-end response that’s frankly surprising given its ultra-slim 100mm profile when wall-mounted. Its solid extruded aluminium build not only looks sharp with sculpted curves and a premium fabric grille but also helps it disappear into any room - unless you want it noticed, in which case, it looks quite stunning too. Thanks to Theory’s advanced DSP-driven approach, the sb25 works as part of a bigger, smarter system where the brain (a rack-mounted Amplified Loudspeaker Controller) lives safely out of sight while driving precision-tuned, full-range performance. Whether you’re fitting out a slick hotel bar, an Atmos mix suite, or your dream media room, the sb25 is the kind of speaker that makes itself at home just about anywhere - and sounds superb doing it.
