1.1.2.-DP-SBENCLOSURE



 

ThisenclosureistobeconfiguredwiththeDP-HtoformtheDP-3livesound

system.



Forbassandsubbassfrequencysoundreinforcement,afoldedhornenclosure

hasbeendevelopedandoptimised,inordertoensurehighperformancelevels

with“kicking”bassesandreallydeepsubbasses.



Special care has been taken in the design and optimisation of the wave-

guidingpartsoftheenclosure,includingthroats,openingsandlengthsof

each one. The result is a best-possible response with a minimum speaker

excursion.Thiswayalinearresponseandabandwidth,reachingfrom45Hz

to220Hz,havebeenachieved,performinganSPLof102dB1W/m.



To configure a DP-3 system, two units are needed, called DP_SB1 and DP-

SB2, which areequal anduse a700W18”speakereach.MUSICSONengineers

havealsooptimisedthisspeaker,inordertoimprovetheirresponsewithin

thistypeofenclosure.



On one hand, a more powerful magnetic structure is used to improve the

speaker’sdynamics,enhancingthetransientresponse.Atthesametime,a4”

(100mm) moving coil, mounted on a Kapton® former, is used. The thermally

efficientcopperiswoundonbothsidesoftheformer,achievinghigherheat

dissipationandstructuralstiffness.Thisallowsthepower applicationof

700WRMS(3000Wpeak).

Alsotheheightofthecoilhasbeenenlarged,inordertoallowagreater

excursion.In order toimprove the coolingofthe coil,twocooling vents

arepresent,differentfromtheconventionalsinglecoolingvent.



Itincludesalsoafrontgrille,coveredwithasturdyfilteringtechnical
