Designed for the most demanding concert and installation audio professionals, the WLA-25 system sets new standards

for astonishing acoustical performance in a compact size.

Line arrays are increasingly employed in a wider range of venues and applications. Frequently these venues have height

or sightline restrictions that limit the placement and size of the array. Rising fuel costs are putting pressure on touring

system providers to downsize their transportation requirements. At the same time, client and audience expectations for

audioperformancehasneverbeenhigher.Tomeettheseneeds,WharfedaleProembarkedonaprogramtodevelopthe

mostcompact,highestoutputlinearrayspeakersystemavailable.

Each WLA-25 element uses a pair of high-power, 5” low-frequency drivers. Both cover low frequencies while only one

extends into the mid range, thus maintaining horizontal dispersion control at a crossover. High frequencies are handled

byapremium1.7”diaphragm,neodymiumcompressiondriver,100°x10°multipleaperturediffractionwaveguide.This

createsawidecoveragewithasuperbstereoimageandallowsformorediverseplacement.

Thewaveguideexitextendsnearlytothetopandbottomoftheenclosuretocreateacontinuousacousticalsourcewith

minimaldiscontinuitiesbetweenadjacentelementsresultingingreatlyreduceddestructiveinteraction.

Premiummaterialsareusedthroughoutthesystem.The enclosureisconstructedofBalticbirchplywoodandcoated

inanenvironmentallyfriendly, waterbornepolymernishthatiseldrepairable.Tokeep the weighttoaminimumand

preventrust,suspensionttingsaremadeofaluminium.

Anelegantlysimple3-pointsuspensionsystemcombinedwithlightweight,compactsizeandexcellenthandling

ergonomicsmeanthataonepersoncrewcaneasilydeployanarray.AsingleWLA-25arrayyframesuspendsupto

twelvelinearrayelementsoruptotwelvelinearrayelements plus onesubwoofer.TheWLA-25systemisequallyat

FEATURES

WLA-25&25SUB MANUAL.indd 3 2017-6-20 9:23:17

TheWLAcanbeconfiguredwithseveraldifferentsplayangles.Thesplayanglesdeterminetheamountofoverlap

betweentheindividualunits.Thisisusedtodeterminetheamountofsummationor‘throw’forseparatesectionsof

thearray.Asthesplayanglebetweenboxesincreasesthesummationdecreasesbutthespectralvariancedueto

interactionsbetweentheelementsisalsodecreased.

Formanyvenuesagoodcompromisebetweenthrowandspectralvariancecanbereachedbyvaryingthesplayangle

acrossthelengthofthearray.Byvaryingtheangularseparationalongthelengthofthearray,abalancecanbemetfor

therequiredcoverage.Smallersplayanglesprovidehigher summationtocovermoredistantseatingandbleachers.

Larger splay angles provide lower summation with reduced spectral variance for close seating. Used correctly this can

provide even coverage over long distances.

EachgroupofloudspeakerswithdifferentsplayanglewillrequireaseparatechannelofamplicationanddifferentEQ

settings.Thisisduetothedifferentsummationeffectsbydifferingsplayangles.

SPLAY ANGLES

Taperingthelevelofenclosureshasabeamsteeringeffectwhichcanbeusedintheconjunctionwithangularseparation

betweenelements.Thebeamwillbesteeredawayfromthe‘on-axis’centrelineofarraytowardthecabsbeingdriven

atthehighestlevel.Theextentofthebeamsteeringeffectdependsonthelengthofthearrayandtheleveldifference

betweenthetopandthebottomofthearray.Thistechniqueallowsyoutofurthertailortheverticalcoveragetodifferently

shapedvenues,reducingthelevelvariancebetweenthefrontandrearofthevenue.

Ideallythelevelofeachenclosureistaperedgradually(e.g.0.5dBor1dBperelement).Thismeansyouwillrequire

anamplierchannelperelementinpassive mode,ortwoamplierchannelsperelementin bi-ampmode.Groupsof

elementscanbetaperedinpairsormore,althoughamoregradualtaperwillgiveyousmootherverticalpatterncontrol.

FLEXIBLE ARRAYS

ArrayscanbeassembledusingonlyWLA-25linearraymodulesorwithWLA-25SUBSubwoofersatthetopofthearray.

TheWLA-25SUBFlyFrameallowsforaWLA-25SUBsubwoofertobeusedatthetopofthearray.TheWLA-25SUBFly

Frame supports up to 12 x WLA-25 modules and 1 x WLA-25SUB with a safety factor of 12.

ArrayscanbeassembledusingonlyWLA-25linearraymodules.ThesmallerWLA-25FlyFramesupportsupto12x

WLA-25 modules with a safety factor of 12.

WLA-25&25SUB MANUAL.indd 5 2017-6-20 9:23:17

Thehighfrequencyperformanceofthemediumandlongthrowsectionsofthelinearraywillbelimitedbyairabsorption.

Asthedistancefromthesourceincreases,themidandhighfrequencieswillbereduced.Theamountofabsorptionata

given frequency is function of pressure, temperature and relative humidity. By far the most important factor is the relative

humidity,althoughtemperaturedoeshaveasignicanteffect.

Toachieveminimalspectralvarianceacrossthecoverageofthearray,thegroupsofloudspeakerscoveringthemiddleto

rearofthevenuewillrequireequalizationtocompensateforthiseffect.Airabsorptionisdifculttopredictwithanygreat

accuracy,andinanycasetherelativehumidityofthevenueislikelytochangewhentheaudiencearriveortheweather

changes. It is important that the venue is monitored during the event as the equalization applied during the design stage

withanemptyvenuemaynotbesuitableduringtheevent.

Asageneralguide,boostabove8kHzforalongthrowgroupofloudspeakersand12kHzforamediumthrowgroupof

loudspeakers.

The chart overleaf shows attenuation in dB/m for a given frequency and humidity. It is important to note that the effects of

airattenuationarelinear,unlikethelevelofattenuationfromdistancefromtheinversesquarelaw.Forexample,at100m

asourcewouldbe40dBdowncomparedtoit’sSPLat1m.Assuming50%relativehumidityand20°thelevelat10kHz

willbeanadditional16dBbelowthis(approximately56dBdown).

AIR ABSORPTION

OPTIMISED GROUND STACKING

WLA-25riggingdoublesupasanoptimizedgroundstackingsystem,usingtheWLA-25SUBsubwooferasabase.Arrays

ofWLA-25linearrayelementscanbeaimeddownwardsbyasmuchas10°tocoveraudienceareasclosetoastage,as

wellasupwardbyasmuchas10°inordertobettercoverdistantbalconyseatingareas.

WLA-25&25SUB MANUAL.indd 6 2017-6-20 9:23:18

AIR ABSORPTION

TheWLA-25hasinternalcrossovers.TheinternalcrossoveroftheWLA-25loudspeakerdividestheaudiosignalintothe

separate frequency ranges for each driver.

TheWLA-25SUBsubwoofersdonothaveinternalcrossovers.Thisfunctionmustbesuppliedbyexternalelectronic

devices such as the Wharfedale Pro Versadrive series or LMX-204.
