Dirac has announced that its Dirac Live Bass Control is now available on a range of AVR models from several manufacturers, including Bryston, Focal and StormAudio (the latter of which we covered here last week). Additionally, products from Arcam, AudioControl and JBL Synthesis, among others, will be soon to follow. The feature allows the intelligent co-optimization of a system’s subwoofers and speakers to deliver consistent and accurate bass throughout a room.

“Speaker and subwoofer sound waves bounce throughout a space and collide with one another to create crossover areas with uneven bass distribution,” stated Thorin. “Dirac Live Bass Control measures and phase corrects both the speakers and subwoofers across all frequencies to produce enhanced bass clarity and improved bass tone evenness throughout the room. It’s a game-changing feature for the home theater industry that’s now available through some of the world’s finest AVRs.”

Dirac Live Bass Control is the second feature offered through the Dirac Live room acoustics product, which also includes the Dirac Live Room Correction room calibration tool. Dirac Live Bass Control aggregates measurement and location data from each subwoofer to determine how a system’s bass is distributed throughout a room. It then identifies gaps in the sound waves and distributes bass evenly across the room. The feature also corrects the low-frequency sound waves produced by a speaker pair, so the bass produced by each speaker is in sync with the system. This allows flexibility for subwoofer placement in a room “without sacrificing performance,” according to the Swedish manufacturer.

All StormAudio, Bryston, and Focal models equipped with Dirac Live Room Correction now include Dirac Live Bass Control (Complete), as will all JBL Synthesis AVRs. Arcam’s AVR10, AVR20, AVR30, and AVR40 units, and AudioControl’s Concert XR-4, XR-6, XR-8 and Maestro X7 and X9 will also soon be equipped with Dirac Live Bass Control Complete.
