The new D.A.S. Variant series was designed

for use in fixed installations, portable A/V, or

requiring and control of the

vertical coverage. The series comprises two models,

the VARIANT 25A which features two 5” speakers for

mid-low frequencies and one compression driver (2”

voice coil and 1 exit) coupled to a plane

wave generator for the high frequencies. The

VARIANT 25A model can be used alone as a frontfill or

under balcony unit for voice reproduction. The second

model is the VARIANT 18A bass system intended to

be used in combination with the VARIANT 25A for

applications requiring extension of the low frequency

rangebelow 90 Hz.

Both units are manufactured using

10/15mm Finnish Birch plywood. The VARIANT 25A

enclosure shape is trapezoidal with 7º angles. The

VARIANT 18A unit is rectangular. Both enclosures

feature a , weather resistant, polyurethane

black paint and incorporate stainless steel and

aluminum captive rigging hardware which is

designed to provide fast, simple and safe rigging by

means of quick release safety pins. Splay angles can

bechanged from 0º to10º in 1º increments.

The components used in the system feature

advanced technologies; new T.A.F. (Total Air Flow)

cooling systems, neodymium magnets which allow

for important weight reductions, titanium diaphragms

for the high frequency sections, and low-mid

frequency cones manufactured using crossed fibers

and elastic suspension that provide exceptional

stability in the vertical plane.

F , the VARIANT 25A

incorporates two 5B 5” speakers with 1” voice coil

and ferrite magnet assemblies in a bass-reflex

configuration. High frequencies are handled by one M-

5N compression driver with 2” voice coil, neodymium

magnet and 1” exit coupled to one plane

wave adapter/ assembly

coherent horizontal dispersion one of the 5” speakers

features a low pass filter, avoiding destructive

interference between the 5” speakers in the mid

frequencyrange.

The VARIANT 18A model includes one 18H

18” speaker with 4” voice coil and neodymium

magnet assembly in a bass-reflex configuration. It can

be flown above the mid-high units or as an

independent cluster.

woofer unit. This amplifier features a high pass filtered

output at 138 Hz intended to provide signal for the

VARIANT25A units.
