DESCRIPTION

   

The new Impulse

™

 1282 is a full range or

bi-ampable two-way enclosure designed
specifically for permanent installation. The
cabinet is constructed of 3/4" Poplar-faced
high-density plywood, or 18 mm, 13-ply all
Birch void-free plywood. The internal flying
points are reinforced with 10 gauge steel
bracing. The decorative and internal
protective grilles are permanently attached to
the enclosure.
   The two-way system is comprised of a
heavy-duty 12" woofer, and a 22XT compres-
sion driver loaded into a CH 3 constant-
directivity horn. The frequency spectrum can
either be divided internally through the
enclosure’s passive crossover operating at
about 800 Hertz, or through an external
active or passive crossover. In either case,
the input lead connection is made secure
through the use of screw terminal barrier
strips for bi-amp operation.

FREQUENCY RESPONSE

   

This measurement is useful in determining

how accurately a given enclosure reproduces
an input signal. The frequency response of
the Impulse 1282 is measured at 1 meter
using a 2.83 volt swept sine input. As shown
in Figure 1, the selected drivers in the
Impulse 1282 combine to give a smooth

frequency response from 60 Hz to 18 kHz.

DIRECTIVITY

   

 Beamwidth and directivity factors are

derived from the -6 dB points from the polar
plots, which are measured in a whole-space
anechoic environment. These are specifica-
tions that provide a reference to the coverage
characterisitics of the enclosure. These
parameters provide insight for proper
enclosure placement and installation in the
chosen environment. The Impulse 1282
exhibits a desirable beamwidth and directivity
factor suitable for all high-level sound
reinforcement applications.
