Connections
Normal Connection
The SB-5218/7218 has barrier strip screw ter-
minals for connection. The terminals accept up
to #10 AWG stranded loudspeaker wiring. Use
the largest wire size and shortest wire length
possible for a given installation. Observe the
polarity markings and keep polarity consistent
throughout the system for best performance.
Parallel Connection of Second SB-5218/7218
The terminals marker SPK2 may be used to con-
nect another SB-5218/7218 in parallel. Connect
the wires as shown in the illustration, at right.
Note: If the SB-5218/7218’s internal wiring has
been modified in any way, this may not func-
tion. If this is the case, remove the terminal cup
and verify the presence of the factory yellow
jumper and blue jumper wires; remedy as
required or have the loudspeaker serviced.
Individual Transducer Connection (requires
modification)
The transducers are wired in parallel inside the
enclosure. If individual transducer connection is
required, remove the terminal cup and remove
the yellow and the blue jumper wires that are
connected between the SPK1 and SPK2 termi-
nals. Replace the terminal cup and mark the
enclosure with a note of the modification.
