*: OptiArray configuration
The Alpha system using a single pair of LS-77s with a total system power capacity of 360W, can sustain 109db SPL at 3m listening distance for the complete system and is thus appropriate for moderate city appartments and condominiums. From this AMR’s OptiArray® configurations extend to the awesome Omega system providing a configuration suited to any size dwelling and listening room. This Omega system consists of 16 pairs of LS-77s in OptiArray® configuration, with a total system power capacity of over 4480W. The Omega system can sustain 134dB SPL at 3m listening distance for the complete system, which is more than many Concert Sound Reinforcement Systems.
