E9
The E9 cabinet is a full range, two way bass-reflex enclosure fitted
with a single 12" LF driver passively connected to a 2" HF
compression driver coupled to a vertically asymmetrical 90° x 50°
CD horn. The asymmetry of the HF horn means that the E9 has a
vertical coverage pattern with a downward tilt. The actual vertical
dispersion is 20° above and 30° below the cabinet axis.
The E9 cabinet is constructed from marine plywood and has 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. The cabinet top plate has an
integral handle and four M10 threaded inserts for mounting
brackets and rigging. The L shaped metal plate at the bottom of
the cabinet also incorporates a handle, four M10 threaded inserts,
a socket to accept a loudspeaker stand and, on the rear panel, two
parallel wired Speakon-NL4 or EP-5 connectors.
The E9 frequency response is truly full range covering a 50 Hz to
17 kHz band - even without an additional subwoofer, this is quite
sufficient for many applications. The wide horizontal and
asymmetric vertical dispersion makes the E9 especially suitable for
close coverage applications up to 15 m (50 ft) where it can be
deployed to best advantage mounted on a high stand.
The E9 can also be used as a stage monitor by simply placing the
cabinet rear side down on stage (baffle angle 45°).
Within a larger system E9s are ideal as delays and for close, wide
coverage work. The precisely angled rear side panels of the
cabinet allow E9 cabinets to be simply placed side by side forming
an array with accurate 90° horizontal coverage per loudspeaker.
To simplify array construction an extensive range of mounting and
rigging accessories are available - please refer to the E-Series
brochure.
The E9 system can be used with the d&b active subwoofer systems
E12-SUB, E18-SUB or C7-SUB. When operated with the P1200A
mainframe the E9 may also be combined with the E15-BX passive
bass extension.
Only operate E9 loudspeakers with a d&b P1200A mainframe
fitted with E9 controller modules or a d&b E-PAC (version 2) in E9
configuration, otherwise there is a risk of damaging the
loudspeaker components.
Connections
The E9 cabinet is fitted with a pair of Speakon-NL4 connectors. All
four pins of both connectors are wired in parallel. The E9 uses the
pin assignments 1+/1. Pins 2+/2 are designated to C and E-
Series active subwoofers. Using one connector as the input, the
second connector allows for direct connection to additional
loudspeakers.
The E9 can be supplied with EP-5 output connectors as an option.
Pin equivalents of Speakon-NL4 and EP-5 connectors are listed in
the table on the left.
