Almost spherical.
For perfect spatial acoustics.

The monitor loudspeakers can be placed separately from the bass loudspeakers to enable the audio system to create outstanding immersive sound. Leaving room for a smooth frequency response across seven octaves.

Design Criteria

Spatial resolution at its best

Monitor M15 starts at 300 Hz in full space

Correction by design

Phase and angle correction of midrange driver and high frequency horn tweeter by mechanical 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 B17 in half space, separated at 300 Hz with Monitor M15 in full space – freedom of location distance between B17 / M15 / wall.

Bass B17 and Monitor M15




2-way passive loudspeaker in an edgeless milled aluminum enclosure with a stainless steel stand

  • Dimensions (W x H x D): 38 x 133 x 54 cm
  • Frequency range: 300 Hz to 22 kHz +/- 2 dB for an average SPL of one third
  • Efficiency: > 95 dB/W/m
  • Max. SPL : 112 dB/m
  • Impedance: 8 ohm

For an interference-free playback of around 300 Hz in the transition zone, the enclosure emission axes of both the monitor and the bass are at the same height despite being in separate enclosures.
