Triad Speakers, Inc., a custom manufacturer of reference-quality loudspeakers for the home, has released its new InWall Bronze/4 SlimSub. 

Measuring 3-15/16 inches deep to fit into a standard 4-inch deep wall cutout, the flat grill, flush mount design of the SlimSub represents an aesthetical improvement over the model it replaces, the InWall Bronze/4 Sub, which protruded several inches from the wall. 

The SlimSub delivers deep bass at high volumes, achieving a maximum output of 109 dB from 40-80 Hz with bass extension of -6dB at 25 Hz. This performance also represents an improvement over the previous model, and according to Triad, rivals that of the company’s larger, 6-inch deep InWall Bronze/6 model. 

According to Triad Speakers president Larry Pexton, the company achieved such rich performance by finely-tuning the sealed enclosure to match the excursion of the proprietary long-throw 10-inch aluminum driver employed. Triad engineers also integrated a round steel back-plate that serves to replace the thick MDF behind the driver, capturing more air volume to accommodate the lengthy throw of the driver.

The SlimSub fits into the same cut-out (size “V”) as the company’s other in-wall subs, making it ideal for retrofit opportunities. To further blend with the décor of most any home, the SlimSub incorporates all 3 types of Triad’s Acoustimesh grill (wide, narrow and frameless) which the company can custom paint-match at the factory.
