4.2 Connecting Upper Speaker Cabinet to Crossover
1. Locate the upper speaker cabinet wiring harnesses: a four-conductor
wiring harness with labels "HIGH" and "MID" for the tweeter and midrange, and
a two-conductor wiring harness with labels "LOW" for the woofer. These
harnesses are hard-wired directly to the upper loudspeaker cabinet drivers
(routed through the wiring tubes in the lower speaker cabinet), in order to
provide the most unobstructed signal path.
2. Connect the upper speaker cabinet wiring harnesses (routed through the
wiring tubes in the lower speaker cabinet) to the OUTPUT terminal block on the
bottom of the crossover cabinet, as shown in Figure 4.1.
Do NOT over-tighten the binding posts.
3. Check to insure the correct polarity: The spade with the RED label connects
to the positive (+) terminal, and the spade with the WHITE label connects to
the negative (-) terminal.
IMPORTANT: Correct polarity of connections is critical to performance. Check
to insure that the RED labeled spade is connected to the positive (+) post and
the WHITE labeled spade is connected to the negative (-) post.
4. Check to insure the correct driver connections: The spades with the "LOW"
label connect to the terminals labeled "LOW", spades with "MID" connect to
terminals with "MID", and spades with "HIGH" connect to terminals with "HIGH".
WARNING: Improper connection of drivers to crossover sections may
instantly destroy the drivers in question. Check all connections carefully
BEFORE power-up.
