Swedish sound technology developer Dirac introduced today Dirac Live Bass Management for the residential AV market.

Dirac Live Bass Management is a unique room acoustics solution that optimizes a system’s subwoofers and speakers to deliver consistent, accurate bass throughout an entire room. The company plans to demonstrate the system at its booth #3235 during CEDIA 2019 in the Colorado Convention Center in Denver, beginning Sept. 12.

Niklas Thorin, Dirac’s GM of High Performance Audio, explained that it had solved the issue of speaker and subwoofer sound waves that tend to bounce throughout a space and collide with one another to create crossover areas with uneven bass distribution.

Dirac Live Bass Management measures and phase corrects a home theater’s speakers and subwoofers across all frequencies, even in multiple subwoofer systems, to produce enhanced bass clarity and improved bass tone evenness throughout the room, the company said.

“Even the most high-end hardware possesses certain performance deficiencies – ones that can only be resolved through an understanding of the room itself,” stated Thorin. “However, while Dirac Live offered new standards in room correction and speaker phase correction, it left one area – the subwoofer’s low-frequency bass tones – unaddressed. The new Dirac Live Bass Management now equips installers and their customers with a tool that addresses this final frontier, moving them one step closer to acoustical perfection.”

The system 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. In the process, Dirac Live Bass Management corrects the low-frequency sound waves produced by the speaker pair, so the bass produced by each speaker is in sync with the system.

The company said that all of this processing enables the subwoofers to be positioned anywhere in the room without sacrificing performance for design.

Dirac Live Bass Management is the first in a series of modular add-ons for Dirac Live, and will be available in two versions: Single-Sub, for single subwoofer home theater systems ($249 suggested retail), and Multi-Sub, for systems with more than one sub, $399.

Among Dirac Live Bass Management implementations in new home theater products, the M10 BluOS streaming amplifier and C658 BluOS streaming DAC will be the first two products from NAD to feature Dirac Live Bass Management.

Depending the specific system, customers will have the option of purchasing the Single-Sub or Multi-Sub options, Dirac said.

StormAudio is set to incorporate Dirac Live Bass Management into its full line of processors and amplifiers while Arcam and JBL Synthesis are slated to incorporate it into the majority of its AVR product portfolio.

At CEDIA 2019, Dirac will deliver a master class session on room acoustics and bass management software, including an inside look at Dirac Live Bass Management. The presentation will take place on Wednesday, Sept. 11th from 10:30 AM to 12:00 PM in Room 1A.
