Theory Professional Previews Full-Range Sound Reinforcement Loudspeaker at InfoComm 2026Following its expansion into the sound reinforcement market in 2025, Theory Professional will be at InfoComm on June 17-19 at the Las Vegas Convention Center, Booth #N6205, to preview a full-range loudspeaker. The extreme output SR-221.3 is the latest addition to Theory's SR Series sound reinforcement loudspeakers and manifold subwoofers. Within its modest enclosure, the SR-221.3 features integral dual 21", 3,600W low frequency drivers, four 10" carbon fiber high-output midrange drivers, and a 5"-wide band ring radiator compression driver mounted on an extremely innovative axi-periodic horn. With a bandwidth of 27Hz - 20kHz, -3dB, approximately 140dB SPL, and ultra-wide 170-by-60-degree coverage, the SR-221.3 is playfully referred to as a "rock concert-in-a-box" because a single loudspeaker can easily fill medium-sized venues with high-output and high-fidelity sound. Billed as surprisingly compact, the high-fidelity SR models won't impede on aesthetics -- they can be installed discretely, and in tighter locations. Along with the other seven models in Theory's SR Series line of sound reinforcement loudspeakers and manifold subwoofers, the SR-221.3 is built-to-order in the US and unites lively dynamics, high maximum output level, and refined acoustic performance. The full-range SR-221.3 will be available in Q4 2026 and will be demonstrated amongst Theory's other highly regarded audio products in audio demo room N212 at InfoComm 2026. Demonstrations will run every even hour Tuesday - Friday (10am, 12pm, 2pm, and 4pm). Schedule a demonstration or stop by Booth #N6205.
