INFRASONICS UNLEASHED

Sleek, Big, Powerful 

If you haven't felt high output infrasonic frequencies, you owe it to yourself to experience the UNRIVALED 21.  With an anechoic frequency response down to 10Hz, single digit in-room frequencies are possible. Pioneering G.A.D.S. UNRIVALED 21 needs a lot of mass to control the raw power of the driver.

 The results are incredibly tight and accurate reproduction with incredible in-room response.  Immerse yourself in the movie with definitive power.

The 21" proprietary driver was co-engineered by RBH Sound and Pierce Audio.  The groundbreaking, low-distortion design made exclusively for RBH features a sandwiched carbon fiber cone, shorting cap, copper sleeve and custom machine work.  Pierce Audio, a privately held company, has built precision subwoofer and speaker drivers by hand in the Pacific Northwest since 2004.  They innovate and engineer the highest quality and resilient subwoofer and speaker drivers for most any application.  For more information, please visit https://pierceaud.io/about/
