JansZen One (in production; other models coming)

  • Two-channel (stereo)
  • 3-way system: Three electrostatic tweeters, six electrostatic midrange/high-woofers, and one electrodynamic low-woofer/sub-woofer
  • Crossovers at 200 Hz and 800 Hz; non-inductive
  • 80 degree tweeter dispersion angle (-3dB at 10 kHz) without facets or curves
  • Varying border width for diffraction peak suppression
  • 12" woofer, semi-custom, ultra low distortion, low mass
  • Three built-in amplifiers per side (tri-amp) providing frequency channel isolation and optimally controlled line level crossover regions -- totally natural sounding, no crossover glitches
  • Reliability assured by stress testing of electronics per applicable parts of MIL-STD-883, and by extreme temperature cycling of ES drivers
  • Can drive directly from a CD player, using its digital volume control
  • Maximum distortion at 85 dB, <0.2% @ 50 Hz to 20 kHz; <0.4% 30 Hz - 50 Hz; < 2.0% @ 15 Hz - 30 Hz
  • Peak SPL between speakers, 3 meters back: 106 dB
  • Frequency response 20 Hz to 20 kHz, +/- 3 dB
  • Bass de-emphasis controls for tailoring rolloff to room size and personal preference: Low bass (-6, -3, 0, +2, +4, +6 dB @ 50 Hz) and sub-sonic (0, -4, -8 dB @ 20 Hz)
  • Input impedance: 20 k Ohm; 1V RMS (2.83V p-p) for full volume
  • Size 19" (48 cm) wide x 12" (30 cm) deep x 72" (183 cm) high
  • Weight (each side) 150 lb (68 kg)
  • Power requirement (each channel) 600W max. (front panel switchable to any mains worldwide)
