CAUTION!
E3
The E3 cabinet is a full range, two way bass-reflex enclosure. Fitted
with a single 6.5" LF driver passively connected to a 1" HF
compression driver coupled to a constant directivity horn with a
90° x 60° dispersion. Illustrated in the drawing on the left is an E3
with the standard 90° horizontal horn configuration. The horn can
be rotated through 90° for a reversed 60° x 90° (h x v) dispersion.
The E3 cabinet is constructed from marine plywood with an impact
resistant paint finish. The front of the loudspeaker cabinet is fitted
with a rigid metal grill covered with a replaceable acoustically
transparent foam. A connector plate with two parallel wired
Speakon connectors, which can be swapped between the rear and
side of the cabinet, together with pairs of M8 threaded inserts for
mounting brackets on each panel allow the E3 to be mounted in
almost any position.
The outstanding feature of the E3 is its neutral sound balance
coupled with an extraordinarily high output capability for a cabinet
of such a size. The E3 frequency response covers a 80 Hz to 17
kHz band making it extremely versatile and ideal for use in near
field, delay, effects, ultra compact monitor and miniature array
systems. Used with an auxiliary subwoofer system, the E3 can also
easily reproduce high level music programs. Suitable subwoofers
are E12-SUB, E18-SUB or C7-SUB.
With an asymmetrical cabinet design and an extensive range of
mounting and rigging accessories (please refer to the E-Series
brochure) E3 cabinets can be mounted or flown almost anywhere
and used in pairs to create 120° or 180° horizontal arrays.
Only operate E3 loudspeakers with a d&b P1200A mainframe
fitted with E3 controller modules or a d&b E-PAC in E3
configuration, otherwise there is a risk of damaging the loud-
speaker components.
Altering the HF horn dispersion
The E3 HF horn has a square flange allowing it to rotate through
90°. Two dispersion angles, 90° and 60°, are engraved on the flange,
the value on the horizontal edge indicates the loudspeakers horizontal
dispersion angle.
To change the horn dispersion, first remove the front grill by
undoing the Allen screws (M4x25 mm) at the top and bottom of the
grill using a 2.5 mm Allen key. Using a 3 mm Allen key, undo the 4
Allen screws (M4x25 mm) which hold the horn in place. The horn
can then be rotated through 90°, refastened and the front grill
replaced.
