X1 Active Crossover

The subwoofer enclosure must be correctly connected to the A1 amplifier and X1 crossover in order to function properly.

X1 Design

The NHT X1 active crossover is designed to allow convenient front panel adjustment necessary to integrate the iWS sub-

NOTE: The X1 contains special equalization circuitry specifically designed for the iWS and Evolution subwoofers. It is not
