In Detail

  • Large scale 1” 99.9% pure magnesium ridge-dome shaped tweeter ideally disperses amp vibration. Powered by 3.6” ferrite magnet with 3.2” boost magnet
  • World-first 5.2” HR shaped 99.9% pure magnesium mid range unit offering high speed sound without metal tone.
  • The HR shaped diaphragm used for the woofer unit disperses unwanted resonance. The seamless connection with the mid range is the basis of this speaker system.
  • CE plywood used for the front baffle, top and sides was specially developed for acoustic use, bonding two different boards (Camphor and Eucalyptus) of different stiffness and density.
  • The front baffle is made of 2 x 18mm CE plywood with a total thickness of 36mm for natural sounding acoustics.
  • The base board is 8 x 9mm MDF with copper feet. Each foot height is adjustable to eliminate any rattling.
  • The hand finished glossy piano enclosure features a magnetically attached front grille.
  • Unique MID Controller adjusts the most sensitive range of 1.6kHz to 6kHz with +1dB to -2dB variable level.
  • The signal through the MID Controller is separated from the tweeter to avoid deterioration of sound quality.
  • Independent network circuitry is used for each woofer to prevent mutual electronic interference. OFC (Oxygen-Free Copper) wire is used for internal wiring and the connecting points are covered with a gold plated sleeve. Input terminal is machined copper with gold plating.
