Checktomakesurethatthesupportsurface
(e.g.oor,etc.)hasthenecessarymechanical
characteristicstosupporttheweightofthe
loudspeaker(s).
Whenpole-mountingloudspeakers,besurethatthey
arestabilizedandsecuredfromfallingoverorbeing
accidentallypushedover.Failuretofollowthese
precautionsmayresultindamagetotheequipment,
personalinjury,ordeath.
Aswithanypoweredcomponents,protectthemfrom
moisture.Avoidinstallingtheloudspeakerinplaces
exposedtoharshweatherconditions.Ifyouaresetting
themupoutdoors,makesuretheyareundercoverifyou

SRMv3loudspeakersareNOTdesignedtoarray
horizontally.Ifyoufeelyoumustputtwospeakers
side-by-side,youshouldhaveagoodunderstanding
oftherelationshipbetweenthesplayangle(theangle
betweenthefacingsidesofthecabinets)andfrequency
cancellationeffectsbetweencabinets.
Whentwocabinetsarepositionedside-by-side
suchthattherear-angledfacesoftheenclosures
areparallel,thesplayanglewillbe90º.Thismatches
the90˚horizontalcoveragepatternofeachindividual
loudspeaker;theinterferencebetweenthetwocabinets
willbeminimized,butthetotalcoverageof180˚may
betoowideforsomeapplications.Themidandhigh
frequenciesmayalsobereducedforthoseinthecenter
whoaretooclosetotheloudspeakers.
Reducingthesplayanglewillreducethetotal
