ALL SPECS SHOULD BE MEASURED AT NOMINAL LINE VOLTAGE.SPEAKER CONNECTIONWhen we designed the E150P, E250P, P10SW and P12SW powered subwoofers, ourgoal was to offer the user the best possible performance combined with the most flexibleand complete installation options.Please look over the following three examples to determine which description bestmatches your system and follow the corresponding hookup instructions.To use the binding-post speaker terminals with bare wire, unscrew the collar until thehole through the center post is visible under the collar. Insert the bare end of the wirethrough the hole in the post, then screw the collar back down until the connection istight. 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 speakerto positive (+) on the amplifier and negative (–) on the speaker to negative (–) on theamplifier. 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 apreferred connection and should only be resorted to if your receiver/processor does nothave a line-level or subwoofer output. The customer is responsible for properconnections, and any damage to JBL or other equipment due to improper connectionswill not be covered by your JBL warranty. Consult with your JBL dealer or an audioinstallation expert if you have any questions about how to connect your subwoofer usingthe speaker-level inputs.6E150P/P10SW subwoofers
