GLASS LOUDSPEAKER

Frequency range : below 16Hz (lowest tuning Q0.5 at 16Hz in 4pi free field) to above 30kHz (-3dB) at +/-1dB from target tuning

Typical THD : below 0.3% at 96dB in the critical mid/high range

directional characteristic : pure monopole below 90Hz, dipole point source above 150Hz, smooth transition with cardioid characteristic in between

Tweeter : (1 per channel): specially developed dipole air-motion transformer with extreme dynamics, ultra-low distortion and very linear amplitude response

Midrange driver : (2 per channel): proprietary 180mm magnesium cone driver with low-inductance linear drive, low mechanical losses, titanium voice coil former and resonances well outside the transmission range

woofer : (2 per channel in force compensated coupling): ultra linear, very long excursion design with extremely stiff 250mm aluminium cone, low mechanical losses and 10kg magnet drive, diaphragm resonances far out of frequency range

Power amplifiers : 1 for the subwoofer, 1 for the midrange / tweeter with 400 W each. Optional semi-active configuration with freely selectable external power amplifier for the mid / high range and one internal power amplifier for each of the two subwoofer speakers (400W + 400W).

Crossover : latest DSP - crossover technology in combination with passive tweeter / midrange crossover, decoupled from internal air pressure fluctuations and vibrations. Optional semi-active configuration with purely passive crossover for the mid / high range for an external power amplifier and DSP - controlled active subwoofer.

Dimensions : approx. 35 x 51 x 110 cm (W x D x H)

Weight : approx. 80 kg
