SPEAKER CONNECTION
When we designed the E150P, E250P, P10SW and P12SW powered subwoofers, our
goal was to offer the user the best possible performance combined with the most flexible
and complete installation options.
Please look over the following three examples to determine which description best
matches your system and follow the corresponding hookup instructions.
To use the binding-post speaker terminals with bare wire, unscrew the collar until the
hole through the center post is visible under the collar. Insert the bare end of the wire
through the hole in the post, then screw the collar back down until the connection is
tight. The holes in the center of the collars are intended for banana-type connectors.
Speakers and electronics terminals have corresponding positive (+) and negative (–)
terminals. It is important to connect both speakers identically: positive (+) on the speaker
to positive (+) on the amplifier and negative (–) on the speaker to negative (–) on the
amplifier. Wiring “out of phase” results in thin sound, weak bass and a poor stereo image.
NOTE:
The speaker-level connection method described on the next page is not a
preferred connection and should only be resorted to if your receiver/processor does not
have a line-level or subwoofer output. The customer is responsible for proper
connections, and any damage to JBL or other equipment due to improper connections
will not be covered by your JBL warranty. Consult with your JBL dealer or an audio
installation expert if you have any questions about how to connect your subwoofer using
the speaker-level inputs.
