Monolith III Specifications

The

MONOLITH III hybrid speaker

system consists of a broad-range
single element electrostatic transducer
integrated with a quick-response
woofer. This approach takes maximum

advantage of the positive aspects that
both technologies have to offer.

Dispersion is a controlled 30 degrees.
This was achieved by curving the

electrostatic transducer element itself,
an elegantly simple solution.

Circuit Topology

Audio circuits are fully complimen-
tary, class-A current-biased J-FET
buffers that isolate passive filter
networks.

Power supply employs a toroidal
transformer , discrete voltage and
self-tracking current regulation.
40-volt peak to peak swing allows
for 30dB of dynamic headroom.

Components

Glass-epoxy boards, metal film
resistors, polypropylene capacitors,
hand picked J-FETs,
