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 several A/V receiver (AVR) manufacturers, Swedish audio technology company Dirac has announced. 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.

Powered by machine learning and AI, Dirac Live Bass Control co-optimizes 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,” noted Thorin in the announcement statement. “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.”

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. This 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. This processing enables the subwoofers to be positioned anywhere in the room for aesthetic reasons, without sacrificing performance for design, or vice versa, says the company.

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.
