Strong bass.
Spacious and transparent depths.

The sleek enclosure of the bass loudspeaker is adjusted both acoustically and optically to the monitor. The bass loudspeakers develop deep, beautifully transparent low-frequency tones without distracting resonances, and over almost five octaves.

Design Criteria

  • Team player. For optimized phase response - Bass B17 in half space, separated at 300 Hz with Monitor M15 in full space – freedom of location distance between B17 / M15 / wall
  • Base for immersive sound – Bass B17 suppresses vertical resonances by design
  • No secondary acoustic emissions, high strength enclosure—by integrating the woofer and bass-reflex openings in an edgeless milled aluminum front panel with all-round braced plastic rear panel
  • Side walls with dished vertical grooves to disperse secondary acoustic reflections
  • Passive crossovers with third-order filters and impedance linearization – Lowest count of film capacitors and shielded inductors, at highest quality – Signal latency below Blauert & Laws criterion, with smooth course
  • Highest quality, high efficiency professional audio driver – No audible frequency modulation – small excursion of driver
  • Fused loudspeaker with power limit circuitry to prevent overload damage




Passivlautsprecher ausgeführt in abgerundeter, hochfester und gefräster Aluminiumfrontplatte und allseitig abgerundeter Kunststoffrückwand.

  • Dimensions (B x H x T): 35 x 210 x 35 cm
  • Frequency range: < 22 Hz to 300 Hz +/- 2 dB for an average SPL of one third and < 20 Hz at - 4 dB
  • Efficiency: > 95 dB/W/m
  • Max. sound pressure: 112 dB/m
  • Impedance: 8 ohm

Since the bass and the monitor are kept separate, they can be set up in an ideal way in any room. For incredible spaciousness and transparency.
