Premium audio brand Theory Professional, is debuting the SR Series, a new line of passive and powered loudspeakers at InfoComm 2025 specifically designed for sound reinforcement applications. The eight new multi-purpose loudspeakers and manifold subwoofers fill a void at the premium end of the market for high output, yet compact and flexible audio solutions for installed and portable applications.
Theory’s new SR Series loudspeakers are built-to-order in the U.S. and unite lively dynamics, high maximum output level, and refined acoustic performance. Unlike most sound reinforcement speakers, and in line with the brand’s promise, Theory is raising the performance bar, not only in terms of accuracy of the reproduced sound, but also in sheer output capability. Surprisingly compact, the powerful, high-fidelity SR models won’t impede on aesthetics – they can be installed discretely, and in tighter locations.
The SR Series was thoughtfully designed from top to bottom including ergonomic handles, multiple fly points, industry-standard mount points, and pole cups. The eight models are available in black and white, and passive or active versions depending on the installation need. Available upgrades include custom paint matching and weatherizing (passive versions only).
Optional accessories include the Theory SplitYokeTM Multipurpose Mounting Brackets used to install the smaller SR Series loudspeakers easily on the wall, ceiling, floor (as a monitor), and other surfaces. An intelligent Caster Kit and Dolly Board are also available making the larger SR Series models portable in an instant. This is especially ideal for DJs, corporate venues, hospitality events, and more where mobile big, clear, full-range sound is required.
“Response from consultants, integrators, dealers, and end-users to our small-format products has been overwhelmingly positive. All of them have requested Theory high-fidelity sound from large format products,” said Paul Hales, CEO and product designer for Theory Professional. “SR Series loudspeakers are specifically designed to fill this niche with a family of products that are flexible, compact, easy to install, but which offer sonic accuracy, clarity, and resolution not available from any other brands in the market segment. They don’t just sound more refined, they look more refined, too. They are truly unique; truly Theory.”
