As originally manufactured, these older cabinets do not function acceptably with single channel full frequency range signals.

The LCO-1 provides an active crossover which keeps low bass signals (below 150 HZ) out of the rotary channel where they could cause damage to the small rotosonic speaker. These signals are routed instead through the stationary channel to the 15" speaker where they are properly handled.
