1092A Active Subwoofer
The 1092A is a compact system that will reproduce frequencies of 33 - 80 Hz (± 2.5 dB). The amplifier unit integrated into the cabinet contains active crossover filters, driver overload protection circuits and a power amplifier. The crossover has 3 signal channels (L/C/R) input and output channels and a discrete subwoofer signal (.1) input, providing great flexibility and allowing easy connection to existing monitor systems, whether one, two or three channel, or to proprietary surround sound decoders. The unit has adjustable sensitivity and a bass roll-off and phase matching control to tailor the response of the subwoofer to its environment.
The combination of the cabinet and amplifier in one unit results in a robust and simple system. The amplifier is mounted on pivoting vibration absorbers, which prevent damage to the electronics and ensures easy access and maintenance of the amplifier.
The cabinet is made from MDF with rounded corners and hardwearing textured black surface. The drivers are concealed inside an efficiency boosting cavity, which also protects them from physical damage.
The 1092A was in production between 1994 and 2003. It was replaced by the LSE™ series subwoofers.
