Børresen BM3 subwoofer
Audio Group Denmark proudly introduces the Børresen Bass Module 3 (BM3) — a breakthrough in low-frequency performance. Designed and handcrafted in Denmark, the BM3 delivers deep, dynamic, and naturally detailed bass that integrates effortlessly with any high-end audio system.
Developed by Michael Børresen and Flemming Erik Rasmussen, the BM3 fuses advanced acoustic engineering with refined industrial design. Its very rare folded dipole architecture eliminates room pressurisation, producing fast, controlled, and distortion-free bass that brings every musical performance to life. The opposing polarities of the folded dipole principle create the desirable in-room cancellation that effectively allows the BM3 to integrate far more easily with the listening environment than a conventional subwoofer.
Superior bass
Driven by a 2 × 300W Aavik UMAC amplifier and four custom 8” DCC8 Neo drivers arranged in a boxer engine configuration, the BM3 delivers extraordinary precision and depth. Its counteractive design eliminates self-generated vibrations, producing a sound that is both powerful and impeccably balanced—infusing every loudspeaker system with lifelike realism and emotional presence.
Børresen technology
Building on the innovations of the acclaimed Børresen T- and M-series loudspeakers, the BM3 integrates advanced technologies for exceptional purity and control:
Folded dipole Architecture for superior room integration
Fully analogue crossover with an adjustable low-pass filter (30–80 Hz)
Ansuz Tesla Coil and analog dither technologies for ultra-low noise
Advanced cabinet construction for optimal mechanical stability and performance
Light, fast, powerful: the BM3 bass drivers
The Børresen BM3 features four 8-inch Børresen DCC8 Neo drivers with spread-tow carbon fiber diaphragms reinforced by an extremely light aramid honeycomb core. This advanced composite delivers exceptional stiffness-to-weight ratio for ultra-fast transient response and minimal distortion. Paired with high-performance neodymium motors and double copper caps, the drivers produce deep, articulate bass with remarkable clarity, speed, and authority.
A heart that sets the pace
The BM3’s integrated amplifiers use the latest Pascal technology with high-speed UMAC switching modulation. With lower noise, reduced filtering requirements, and minimal output impedance, it delivers precise control over the four drivers, ensuring dynamic, accurate, and high-resolution bass performance across the full frequency range.
Crossover technology that redefines bass control
The BM3 incorporates an adjustable, fully analog low-pass crossover that integrates with virtually any loudspeaker, introducing no signal delay for perfect time alignment. It precisely filters higher frequencies so the BM3 reproduces only the intended bass range, shaping the roll-off to manage transitions, reduce overlap and distortion, and deliver tight, accurate, and seamlessly controlled low-end performance with enhanced overall clarity.
