Pro Audio Technology (PRO) announces a new loudspeaker model, the SR-28212ai – the company’s most acoustically ambitious and flexible loudspeaker. 

The SR-28212ai features a 1.7-inch advanced polymer compression tweeter, two ultra-high output 8-inch midrange drivers, and two 12-inch, 2000W woofers inside a distinctive, aimable enclosure. It serves as three loudspeakers in one: a very high-output, very 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 within a single 6-inch-deep 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 text-book-perfect on and off-axis dispersion of critical high frequencies.

“By leveraging the bass-management capability of our ALC model amplified loudspeaker controllers, a single SR-28212ai loudspeaker system can serve as a full-range surround loudspeaker, an auxiliary LFE system subwoofer and a surround speaker bass-management subwoofer, simultaneously,” says Paul Hales, president and product designer, Pro Audio Technology. “For example, 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”.

The Future of Digital Lighting & Control

As a custom integrator, lighting is in demand. Effective communication, education and showcasing the value proposition of LED light fixtures in conjunction with integrative control systems are the keys to overcoming challenges and closing sales in this specialized market.

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. 

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 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.

“I’m not aware of a more powerful or flexible loudspeaker system anywhere,” says Hales. “Combined with our ALC bass-management and mixing capabilities, there is almost no application it cannot handle.”
