Installation
Toachievethebestpossibleintelligibilityandsoundqualitywithacolumnspeaker,youneed
topayextraattentionsothatthemountingofthespeakerisdoneproperly.Thedimensions
ofthedesiredlisteningareahavetobedeterminedfromwhichthecorrectmountingheight
andanglecanbederived.
Astepbystepinstallationproceduredescribesthemethodtodeterminethemountingheight
andanglefortheAXIR.
DETERMINING LISTENING AREA AND MOUNTING HEIGHT

STEP 1:
DeterminethedimensionsofthedesiredListeningArea.Thisisahorizontalplaneatthe
samelevelasthelistenersears.Refertothedashedlineinfollowingfigure.
STEP 2:
Nowthatthelisteningareaisknown,determineatwhichangletheloudspeakerarray
shouldbemounted.TheAXIRcolumnspeakerwasdesignedtoaimthesoundjust
abovetheheadsofthelisteners,anditisrecommendednottoexceedanangleof6°.
Therearetwodifferentapproachestodeterminethemountingangle,eachwithspecific
advantagesanddisadvantages.Whichapproachyouchoose,dependsonwhatyouwant
toachieve:amaximumlisteningareaoraminimalvariationinsoundpressurelevel.


- Approach 1: Maximum listening area
Whenalargelisteningareaisdesired,anangleofaround3°isrecommended.When
youmoveawayfromtheloudspeaker,thesoundpressurelevelwillbedecreased.This
decreasedependsonthereverberationoftheroominwhichthespeakerisplaced.
Ifyouwantthehightonestobeclearlyaudible,makesurethelistenerisabletoseethe
loudspeakerarray.
- Approach 2: Minimal variation in sound pressure level
Whenaminimalvariationinsoundpressurelevelisdesired,anangleof5°isideal.The
sizeofthetotallisteningareabecomessmallercomparedtothepreviousapproach.The
spacenearbytheloudspeaker‘A’doesnotbelongtothelisteningarea.
(Diagram1showstherelationshipbetween‘A’andthemountingheightofthe
loudspeakerwhenusinganangleof5°)

STEP 3:
Whenyou’vechosenoneoftheapproachesabovetodetermineyourmountingangle,you
proceedbydeterminingthemountingheight.Thisheightisdeterminedbyaimingthe0°
axisoftheAXIRinthedesiredposition,preciselyabovetheearlevelofthelistenerwho’s
thefurthestawayfromthespeaker.Thiscanbeadjustedbymountingtheloudspeaker
higherandloweronthewall.
STEP 4:
Whenyou’vedeterminedthemountingangleandheight,youcanstartinstallingthe
speaker.

OTHER POINTS TO PAY ATTENTION TO:
Whilemountingacolumnspeaker,therearestillsomeotherpointsyouneedtopay
attentionto.
-Makesurethattheloudspeakerarrayisalwaysvisibleforeveryoneinthelistening-
area,thisensuresagoodaudibilityofthehightones.Hightonescanbecomparedwith

Forhightones,thesamethingcanbesaid.Whensomeoneisstandingbetweenthe
listenerandtheloudspeaker,thelistenerislocatedinthe“soundshadow”.The“sound
shadow”willbeexperiencedasareductionofhightones.
-Whentheloudspeakerisinstalledataverysmallangle,alargelisteningareacanbe
achieved.Dependingontheamountofreverberationintheroomandthe“soundsha-
dow”,thespeechintelligibilityonafarpositionmaybelow.Inthissituation,itisrecom-
mendedtousemoreloudspeakerarraystosplitthelisteningarea.
-Whenyoumovefurtherthanthemaximumpositionofthelisteningarea(furtherthan
themaximumdistanceoftheloudspeakerarray),onlythesoundpressurelevelwillde-

pressureleveldependsstronglyonthereverberationoftheroom.

-Becausetheloudspeakersaredesignedtobeamthesoundjustabovethelisteners
