1092A

Drivers
The 1092A uses two 210mm (8") cone drivers with large magnets and displacement capability. The drivers are housed in a 55 liters vented cabinet and they are front loaded to improve passband efficiency and to improve the stopband rejection.

Amplifier
The amplifier produces 180 W of short term RMS power, with very low THD and IM distortions. The amplifier includes circuitry for driver overload and thermal overload protection ensuring the long term reliability of the drivers. The unit also contains a muting circuit disconnecting the amplifier and filter outputs when the mains power is switched on and off to prevent pops and clicks.
