1.1.1.-DP-HENCLOSURE


The DP-H enclosure is an active-two-way acoustic system to reproduce
high-mid frequencies, conceived as al long-throw unit for great musical
indoorandoutdoorevents.

Bothwaysarebuiltontotheirownhorn,optimisedtocompletelycontrol
theirdispersionangles.

Forthereproductionofthemediumfrequencies,a12”speakerwitha3”
(77mm)movingcoil,mountedonanenhancedmagneticsystem,hasbeenused
in order to increase performance without increasing harmonic distortion.
Also, theoutput surface has been reducedto14cm(5.5”)toincreaseits
efficiency.Thishasbeenachievedthroughthedesignofaninnovativephase
plug,builtwiththreeconcentricindependentpieces.Thisallowsustohave
a constant distance between the cone surface and the throat, eliminating
phase cancellations produced in other phase plug types such as ob’s or
bullets. The speaker also features cooling elements for the moving coil,
allowing higher power levels and, at the same time, and much lower power
compression through heat. The cone has received a special coating that
avoids deformation through higher-pressure levels, translated into lower
harmonicdistortionathighpower levelsandprotectingitagainstadverse
external agents such as humidity. Through all this an extremely flat
frequencyresponseupto1200Hzisachieved(togetherwiththeuseofthe
