This diagram shows the left and right line level outputs of a Mackie Onyx 1640i mixer feeding input A of two Mackie HD1501 subwoofers. The Full Range output A of each subwoofer then feeds input A of another pair of Mackie HD1501 subwoofers. The High Pass output A of these subwoofers also feed the input of each Mackie HD1521 loudspeaker. Be sure to disengage the Polarity Invert switch on the HD1501 subwoofers to optimize performance.
