3 Phase Orientaon: Once inthe cornerwe needtoadjustforphase.This maybe thesingle mostcrical
stepand, becauseitreallyis quitesimple, itis oenover-thought.Keepin mind;therightphase is
whicheverposionisthe loudestorfullest.While playing musicwithtrue lowbass,adjust thecrossover
toapoint where the RELand thespeakeraresuretosharefrequencies(about halfway up orslightly
higherforsmallerspeakers).Atthispoint turn theHI/LOWlevelcontrolupso thatboththe RELand
speakerareroughlyequal involumeand thenswitch,usingthe phaseswitch,from“0”to“180” phase
posions.Again,whicheverposionisloudestorfullestisthecorrectposion.Thatis,whentheposion

4 Placement: Thenextstepisto determinepreciselyhow far outfromthecornerthe subshould beplaced
toachievethemostefficientoutput, aswellas thelowestfrequencyextension.With theRELfully into
thecorner,and poinngstraightout alongthediagonal comingoutof thecorner,connuingtoplaythe
music,slowlypull theREL fromthe corneronthe diagonal,equidistantfromboth sideand rear wall. Ata
