SPEAKER PLACEMENT• As a general rule, bassresponse increases as asubwoofer is placed closerto a wall. Therefore, bassoutput is maximized whenthe subwoofer is placed ina corner.• It is also recommended thatthe subwoofer be positionedalong the same wall as thefront loudspeakers.Low-frequency sounds are nor-mally omnidirectional, meaningthe listener can’t tell where theyare generated from. However,frequencies between 75Hz and150Hz can be localized, espe-cially at higher volume levels.Positioning your subwoofer asrecommended will provide themost natural soundstage andimaging from your loudspeakersystem.Remember that these are justguidelines. Since every listeningroom is different, JBL stronglyrecommends experimentingwith the positioning of yoursubwoofer to obtain the mostpleasing results in your room.One technique that can helpyou find the ideal subwooferlocation is to temporarily placethe subwoofer near the mainlistening location. Then movearound the room and determinewhere you hear the mostpleasing bass performance.This would then be the ideallocation for the subwoofer.SPEAKER CONNECTIONWhen we designed theP10SW and P12SW poweredsubwoofers, our goal wasto offer the user the best pos-sible performance combinedwith the most flexible andcomplete installation options.Please look over the followingthree examples to determinewhich description bestmatches your system andfollow the correspondinghookup instructions.To use the binding-postspeaker terminals with barewire, unscrew the collar untilthe hole through the centerpost is visible under the collar.Insert the bare end of the wirethrough the hole in the post,then screw the collar backdown until the connection istight. The holes in the centerof the collars are intended forbanana-type connectors.Speakers and electronics termi-nals have corresponding positive(+) and negative (–) terminals. It isimportant to connect bothspeakers identically: positive (+)on the speaker to positive (+) onthe amplifier and negative (–) onthe speaker to negative (–) onthe amplifier. Wiring “out ofphase” results in thin sound,weak bass and a poor stereoimage.NOTE: The speaker-level con-nection method described onpage 4 is not a preferred con-nection and should only beresorted to if your receiver/processor does not have aline-level or subwoofer output.The customer is responsible forproper connections, and anydamage to JBL or other equip-ment due to improper connec-tions will not be covered byyour JBL warranty. Consult withyour JBL dealer or an audio-installation expert if you haveany questions about how toconnect your subwoofer usingthe speaker-level inputs.3THANK YOU FOR CHOOSING JBLFor more than 60 years, JBLhas been involved in everyaspect of music and filmrecording and reproduction,from live performances tothe recordings you play inyour home, car or office.We’re confident that the JBLsystem you have chosen willprovide every note of enjoy-ment that you expected –and that when you thinkabout purchasing additionalaudio equipment for yourhome, car or office, you willonce again choose JBL.Please take a moment toregister your product on ourWeb site at www.jbl.com.This enables us to keep youposted on our latest advance-ments, and helps us to betterunderstand our customersand build products thatmeet their needs andexpectations.JBL Consumer Products
