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.
