Dirac is bringing Dirac Live Bass Control to select NAD streaming amplifiers, giving owners of the M33, M33 V2, M10, M10 V2, M10 V3, and C 658 a more advanced way to fix the part of stereo playback that usually behaves like it has outstanding warrants: the bass.
Available as an optional $299 software upgrade, Dirac Live Bass Control builds on the Dirac Live Room Correction already included with these NAD models and uses measurement data from each subwoofer to analyze how bass is distributed throughout the room. The software then identifies gaps, resonances, and uneven low-frequency behavior, helping deliver smoother crossover integration between speakers and subwoofers, more consistent bass across the listening area, better multi-subwoofer management, and greater flexibility in subwoofer placement.
To use Dirac Live Bass Control, NAD owners will need to update their streaming amplifier to BluOS version 4.16.6. A Dirac Calibration Mic Kit is also available separately for NAD products.
“The integration of Dirac Live Bass Control into select NAD amps marks a strong step forward, expanding Dirac’s market presence while enhancing the audio performance of NAD’s renowned lineup,” stated Rikard Hellerfelt, VP and Head of Consumer Electronics at Dirac. “Traditionally, configuring subwoofers for optimal performance has been complex and often imprecise. Our advanced bass control technology co-optimizes subwoofers and speakers, creating a seamless blend at the crossover point. This innovation eliminates seat-to-seat sound variation, delivering impactful bass that’s free of unwanted reflections and boominess – making premium bass quality accessible to everyone, from professional installers and audiophiles to everyday consumers.”
Dirac Live Bass Control goes beyond basic room correction by time-aligning all speakers and adjusting low-frequency phase so the subwoofers and main speakers behave like one system, not a custody dispute. That matters because bass is usually where rooms do their worst work.
The upgrade allows NAD M33, M33 V2, M10, M10 V2, M10 V3, and C 658 owners to co-optimize their speakers and subwoofers for a smoother blend between low and higher frequencies, while also giving them more freedom to place subs where they actually fit in the room. These BluOS-enabled NAD components can also store multiple Dirac filter presets for different listening positions or room conditions, with quick switching available through the BluOS Controller app.
What Is Dirac Live Bass Control and Why Does It Matter?
Dirac Live Bass Control is designed to help users get better bass from one or more subwoofers by analyzing how low frequencies are distributed throughout the room. It uses measurement and location data from each subwoofer, identifies uneven bass response, and applies correction so the low end is more consistent across the listening area.
It also corrects the timing relationship between the subwoofers and the main speaker pair, helping the system behave more like one properly integrated source instead of three boxes arguing in a basement. The result is smoother bass through the crossover region, tighter low-frequency response, more effective multi-subwoofer management, and greater flexibility when it comes to subwoofer placement without completely sacrificing performance.
Dirac Live Bass Control sits within the broader Dirac Live family, which also includes Dirac Live Room Correction. That platform is already used across a range of products from Onkyo, Pioneer, Integra, Denon, and Marantz, and is designed to improve imaging, clarity, speech intelligibility, and low-frequency control by reducing room-related resonances across the listening area.
The Bottom Line
Dirac Live Bass Control on select NAD streaming amplifiers is for listeners who already invested in serious two-channel systems and want better bass integration without swapping hardware or turning the room into an acoustic science fair. If you use one or more subwoofers with the NAD M33, M33 V2, M10, M10 V2, M10 V3, or C 658, this upgrade matters because it addresses timing, phase, crossover blending, and bass consistency across the room — not just the sweet spot.
What makes it useful is the flexibility. Multiple Dirac filter presets can be stored for different seats or room conditions and changed from the BluOS Controller app. Drapes open, drapes closed, different listening position, different bass behavior. Very fancy. Very real. Just remember: Dirac Live Bass Control is an optional $299 license upgrade, not a free NAD firmware gift from the audio gods.
