The SR-28212ai is the highest-performance, most versatile loudspeaker system Pro Audio Technology has ever produced.

The SR-28212ai is a large format multipurpose loudspeaker with built in subwoofer system, designed for ultimate accuracy, resolution and unrestricted dynamics. Though only 6 inch deep, the SR-28212ai produces surprisingly full-range, visceral sound typically only found in much larger loudspeakers. The SR-28212ai is the first PRO model to utilize our new Theorem™ axi-symmetric waveguide with wide-bandwidth Ultra-Purity™ high-frequency compression driver to provide ideal dispersion of highfrequency energy. The sound is clean, pure and coherent with no trace whatsoever of compression driver harshness.

A first in high-end residential audio, with its built-in subwoofer section, the SR-28212ai can serve as three speakers simulaneously: wide-bandwidth full-range loudspeaker, surround subwoofer for bass management and main LFE subwoofer to reproduce the low frequency effects channel content - all in an easy-to-locate 6 inch deep enclosure. As in commercial and professional audio systems, the SR-28212ai is tri-amplified to maximize the performance of each driver section in the system. With maximum output exceeding 130dB, it is the ideal choice for screen channel or reference applications in small, medium, and large sized rooms where loudspeaker depth limitations might be a concern.

The subjective and measured performance of the SR-28212ai is so good it can be successfully used as a reference monitor in studios and other applications where absolute accuracy and high resolution are required.
