As Pro Audio Technology (PRO) explains, by leveraging the bass-management capability of the company's ALC model amplified loudspeaker controllers, a single SR-28212ai loudspeaker system serves as three loudspeakers in one: a very high-output, full-range loudspeaker for LCR or surround applications, an LFE (main) subwoofer, and a subwoofer for surround and Atmos speaker bass management – all at the same time, and all from the same thin enclosure.
Designed with residential surround sound systems (including DCI) in mind, the SR-28212ai can be configured with straight-firing axi-symmetric, or 40-degree asymmetric waveguides which aim the sound at a 40 degree angle to the loudspeaker’s main axis. This allows the sound to be “aimed” at the reference listening position while the speaker is mounted flush in a flat architectural wall. The SR-28212ai is also the first PRO product to utilize PRO’s new Theorem Waveguide, which offers on and off-axis dispersion of critical high frequencies.
Fully aimable using PRO’s pivot brackets, the SR-28212ai provides a very wide dispersion, is incredibly efficient (>100dB/W in every passband) and offers massive output at over 130dB. The low frequency section is 102dB sensitivity (with 4000W, 2000W AES, power handling); mid frequency is 106dB (1000W, 500W AES, power handling); and high frequency is 108dB / Watt.
For in depth-constrained systems where the speakers cannot be aimed, the SR-28212ai can also be ordered with a 40-degree waveguide to aim high frequencies at 40 degrees when mounted flat. To further increase utility, the mid-tweeter module can be inverted to bring the tweeter level down or locate it in the center of the enclosure for horizontal use, such as under or over video walls, with either a 0-degree or 40-degree waveguide.
Alternatively, an installer could invert the mid-tweeter baffle and mount the speaker upside down, placing the subwoofer section near the ceiling for use as a surround sub to augment Dolby Atmos speakers while keeping the midrange drivers and tweeters in the correct orientation and at the proper height. Extremely flexible, the SR-28212ai 40-degree asymmetric waveguides can be rotated in 90-degree increments to fire in any direction: left, right, up, or down.
“In space or budget-constrained systems, three 6-inch deep 28212ais can operate as the LCR speakers and three main LFE subwoofers. There is no need to buy or locate separate subs. I’m not aware of a more powerful or flexible loudspeaker system anywhere,” says Paul Hales, President and Product Designer, Pro Audio Technology. “Combined with our ALC bass-management and mixing capabilities, there is almost no application it cannot handle.”
Pro Audio Technology designs and manufactures a complete range of loudspeakers and DSP amplified loudspeaker controllers for high-end residential installations. All PRO products are designed, engineered and manufactured in the US.
The SR-28212ai loudspeakers are now available worldwide. For pricing, interested dealers, reps, and international distributors can contact Mark Goldman here.
