2.5-way reference grade monitors with proprietary lumen white driver-, port-, loading- and air-damping-technologies. sensitivity 91 db.

drivers, cabinet, crossover and components designed, selected and matched for best-in-class spectrum fidelity, impulse precision, time- and phase-coherence, inter-octave energy balance, signal rise- and settling times and freedom from impulse-memory and signal-shadowing effects.

cabinet constructed from custom made, variable density, resonance balanced, multiple tonewoods based, instrument-grade plywood.

acoustically superior to synthetic, metal and most solid wood enclosures due to a superior, balanced resonance-spectrum and a natural, psychoacoustically vanishing sonic signature.

latest generation, custom-specced, ceramic driver array with class leading, sonically "vanishing" spectrum profile when compared to alternative metal, plastic, polymer and compound membrane technologies.

proprietary, purist, time-, impulse- and magnetic field interaction optimized, minimal-phase design crossover. switchable bass accenture/ boost facility.
