Børresen sub – The Bass Module 3 [$21K] combines two opposing hence force-cancelling pairs of 8" spread-tow carbon-fibre woofers for compound ~15" surface in a folded open baffle design reminiscent of Axel Ridthaler's RiPol aka Ridthaler Dipole geometry previously seen at Ecobox, ModalAkustik, sound|kaos and Voxativ. A 300wpc stereo amp based on Pascal class D modules and analog 4th-order low-pass crossover with 11 frequency selections between 30-80Hz plus ±6dB gain adjustment in ¼dB steps house in the integral plinth with dot-matrix display. The brand's proprietary noise cancellation includes 36 active Tesla coils, 72 square Tesla coils plus three analogue dither circuits and two golden aerial resonance coils. Basic specs are max 4.5/9Vrms stereo/mono inputs at 10kΩ; dimensions of 58x40x43cm HxWxD, weight of 46.4kg and bandwidth of 20-120Hz, no SPL limits given. The finish is high gloss black with carbon details.
