HD1801: 3-WAY SYSTEM - MONO SUBWOOFER WITH HD1521 LOUDSPEAKERS

This diagram shows the left line level output of a Mackie 1604-VLZ3 mixer feeding input A of one 

Mackie HD1801 subwoofer. Two HD1521 loudspeaker inputs are fed from the A and B High Pass    

outputs from the subwoofer. Experiment with the HD1801’s polarity switch to achieve optimum  

performance. Placement of the subwoofer relative to the full-range loudspeakers will also affect  

performance. See page 10 for more information.
