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

Base for immersive sound

Bass B19 suppresses vertical resonances by design

No secondary acoustic emissions

high strength enclosure—through loudspeaker enclosures in an edgeless milled aluminum shape. Side walls with dished vertical grooves to disperse secondary acoustic reflections.

Highest quality, high efficiency professional audio drivers

No audible frequency modulation – small excursion of driver

Fused Loudspeakers

Fused loudspeakers with power limit circuitry to prevent overload damage

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

Team player. For optimized phase response.

Bass B19 in half space, separated at 300 Hz with Monitor M15 in full space – freedom of location distance between B19 / M15 / wall.

Bass B17 and Monitor M15




Passive loudspeaker in an edgeless milled aluminum front panel with all-round braced plastics rear panel.

  • Dimensions (B x H x T): 35 x 210 x 35 cm
  • Frequency range: < 20 Hz to 300 Hz +/- 2 dB for an average SPL of one third
  • 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.
