Dirac Live Bass Control Now Available in Home Theater AVRs

Swedish sound pioneer Dirac today announced that Dirac Live Bass Control, the latest feature of Dirac Live, is now officially available for home theater and audio enthusiasts in a range of models from a series of leading AVR manufacturers.

Powered by machine learning and AI, Dirac Live Bass Control intelligently co-optimizes a system’s subwoofers and speakers to deliver consistent and accurate bass throughout an entire room.

According to Niklas Thorin, Dirac’s GM of high-performance audio, the solution is now featured on AVR units from Bryston, Focal and StormAudio, with units from Arcam, AudioControl, JBL Synthesis, and others soon to follow.

“Speaker and subwoofer sound waves bounce throughout a space and collide with one another to create crossover areas with uneven bass distribution,” Thorin stated. “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 Dirac Live Room Correction, the industry’s reference and award-winning room calibration tool.

The newest feature is available in three tiers: Enabled, for manual single subwoofer management; Limited, for automatic single subwoofer management; and Complete, for AI multi-subwoofer management.

Dirac Live Bass Control aggregates measurement and location data from each subwoofer to determine how a system’s bass is distributed throughout the 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 the speaker pair, so the bass produced by each speaker is in sync with the system.

All of this processing enables the subwoofers to be positioned anywhere in the room – wherever most aesthetically pleasing – without sacrificing performance for design, or vice versa.

All StormAudio, Bryston, and Focal models currently equipped with Dirac Live Room Correction are now also equipped with Dirac Live Bass Control (Complete), as will soon be true of 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.
