Developed and manufactured in Denmark, the Børresen Bass Module embodies decades of loudspeaker innovation. From its advanced folded dipole architecture to its fully analogue crossover and dedicated amplification, every element is designed to minimize noise, distortion, and room interaction. The result is bass reproduction that is fast, clean, and seamlessly integrated — not added on.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES \u0026amp; SYSTEM HIGHLIGHTS\u003c\/h3\u003e\n\u003cul\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eOverview:\u003c\/strong\u003e The Børresen Bass Module 3 is an active subwoofer designed to deliver deep, fast, and highly controlled bass performance. Powered by a high-efficiency Class D Pascal amplification module, it combines power and precision to seamlessly extend low-frequency response. Engineered to integrate effortlessly with Børresen loudspeakers and high-end audio systems, the Bass Module 3 enhances musical realism with clarity, authority, and control.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eUnique Crossover Topology:\u003c\/strong\u003e The Børresen Bass Module features a fully analogue low-pass crossover derived directly from advanced Aavik amplifier designs. Unlike conventional subwoofers that rely on DSP-based filtering, this analogue topology avoids signal delay and preserves timing accuracy. The crossover allows precise selection of cut-off frequencies between 30–80 Hz with a fixed 24 dB\/octave slope, ensuring a natural and seamless transition. Fine level adjustment in 0.25 dB steps enables exact bass integration, while the internal crossover can be bypassed when using compatible Aavik electronics.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eResonant-Mode Power Supply:\u003c\/strong\u003e The Børresen Bass Module employs a power-factor-corrected resonant-mode switching power supply engineered specifically for its Class-D amplification stage. Operating with sine-wave behaviour rather than square-wave switching, this supply delivers extremely low noise and exceptionally fast current response. As power demand increases, operating frequency rises to maintain stability and control. The result is vanishingly low output impedance, superior driver control, and a consistently low noise floor even under demanding musical conditions.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eAdvanced Noise Rejection:\u003c\/strong\u003e Noise rejection is fundamental to the performance of the Børresen Bass Module. Acoustic, electrical, and airborne noise are addressed through a comprehensive system of technologies developed across Audio Group Denmark. Active Tesla coils and active square Tesla coils suppress voltage spikes through counter-phase cancellation, dramatically lowering the noise floor. Analog Dither Technology amplifies the music signal while reducing background noise within the crossover circuits. Anti-Aerial Resonance Coil technology prevents RF interference from entering the signal path by absorbing and eliminating airborne noise. Together, these technologies create a purer, quieter environment where musical detail, clarity, and spatial definition can fully emerge.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eIn-House Production \u0026amp; Quality Control:\u003c\/strong\u003e Every Børresen Bass Module is assembled by hand at our Aalborg facility in Denmark. Our production combines advanced in-house capabilities — including CNC machining, cryogenic processing, and precision assembly — with carefully selected specialist partners. Each component is inspected, measured, and tested step by step to ensure consistency with the reference model. Final voicing is performed by ear, because every loudspeaker must sound exactly as intended before it leaves our factory.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eMechanical Grounding:\u003c\/strong\u003e Mechanical grounding plays a crucial role in the performance of the Børresen Bass Module. While its folded dipole design inherently generates fewer vibrations than conventional subwoofers, optimal results are achieved when unwanted resonances are effectively controlled. Ansuz Darkz resonance control devices decouple the bass module from the floor while providing a controlled path for internal vibrations to dissipate. This prevents resonance feedback, lowers noise, and enhances bass precision, clarity, and dynamic control — making Darkz an integral part of the BBM's performance potential.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch1\u003eSPECIFICATIONS\u003c\/h1\u003e\n\n\u003ctable style=\"width: 100%; border-collapse: collapse;\"\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color: #f2f2f2;\"\u003e\n      \u003cth style=\"text-align: left; padding: 8px;\"\u003eSpecification\u003c\/th\u003e\n      \u003cth style=\"text-align: left; padding: 8px;\"\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px;\"\u003eDimensions (Metric)\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px;\"\u003e585 mm (H) x 399 mm (W) x 429 mm (D)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px;\"\u003eDimensions (Imperial)\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px;\"\u003e23.03 in (H) x 15.71 in (W) x 16.89 in (D)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px;\"\u003eWeight\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px;\"\u003e46.4 kg \/ 102.3 lbs\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px;\"\u003eFrequency Response\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px;\"\u003e20 Hz - 120 Hz\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px;\"\u003eDrivers\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px;\"\u003e4 x Børresen DCC8 Neo\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px;\"\u003eLine Input\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px;\"\u003eMax input 9V RMS (mono) or 4.5V RMS (stereo)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px;\"\u003eInput Impedance\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px;\"\u003e10kΩ\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px;\"\u003eVolume Control\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px;\"\u003e56 x 0.5dB steps\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px;\"\u003eNoise Reduction\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px;\"\u003e36 Active Tesla Coils | 72 Active Square Tesla Coils | 3 Dither Circuitry | 3 Anti-Aerial Resonance Coils\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px;\"\u003ePower Consumption\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px;\"\u003eStandby: \u0026lt;1W | Idle: \u0026lt;30W\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px;\"\u003eInput Voltage \/ Current\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px;\"\u003eMax current 10 A\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px;\"\u003eEnclosure IP Rating\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px;\"\u003eIP20\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px;\"\u003eFinish\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px;\"\u003eHigh gloss black with carbon details\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Borresen","offers":[{"title":"Default Title","offer_id":53776151904522,"sku":"BORR-BM3-ABM","price":18000.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0917\/3283\/6618\/files\/borresen-bm3-active-bass-module-51330-p_95af9e20-6eab-493d-8a2a-026d60e5f4cc.png?v=1789921463","url":"https:\/\/audioemotion.co.uk\/products\/borresen-bm3-active-bass-module","provider":"Audio Emotion Limited","version":"1.0","type":"link"}
