Open the crossover housing by firmly squeezing the sides of
the top half and lifting it away from the bottom. Using screws
or a wire tie, mount the crossover using the holes provided.
Observing proper polarity, connect the speakers and amplifier
as shown in Figures 8A and 8B. Replace the cover when you
are finished making the connections and adjustments (see
following section).

are wired similarly.

The Power Series component crossover features a 
tweeter-level adjustment. The tweeter level may be set to 0dB
(flat response), or it may be attenuated by approximately 3dB
to suit the listener’s preference. The factory default position is
0dB; if this is the desired setting, it is not necessary to make
any changes.

If a reduced tweeter output level is desired, carefully remove
the small plastic jumper from the pins marked “0dB” and place
it across the two pins marked “–3dB” (refer to drawings
below).
