E15-BX
The E15-BX passive subwoofer system is used to extend the low
frequency range of the E9 loudspeaker. The E15-BX bass-reflex
cabinet is fitted with a single 15" driver and an internal passive
crossover.
The E15-BX cabinet is constructed from marine plywood, fitted with
steel handles and has an impact resistant paint finish. The front of
the loudspeaker cabinet is fitted with a rigid metal grill and
covered with a replacable acoustically transparent foam. Mounted
on the rear panel are two Speakon NL4 or EP-5 connectors wired
in parallel and on the top panel an M20 threaded flange to accept
the d&b Z5013 loudspeaker stand for the deployment of full range
cabinets.
The passive crossover network has a cutoff frequency of 150 Hz.
The E15-BX can be connected in parallel with an E9 or MAX
cabinet without active filtering. No additional electronics are
required.
Driving an E15-BX in parallel with other full range loudspeakers
like E3, C6 or C7-TOP is not practicable, because their respective
controllers only transmit the frequency range above 80 Hz (E3) or
70 Hz (C6, C7).
Only operate E15-BX loudspeakers with a d&b P1200A mainframe
fitted with E9, ampMAX or AMP-L controller modules. As an
alternative other high quality power amplifiers may be used,
provided their output power does not exceed 500 watts into 8
ohms and an additional subsonic filter is used (25 Hz with 12 dB/
octave minimum), otherwise there is a risk of damaging the
loudspeaker components.
Connections
The E15-BX cabinet is fitted with a pair of Speakon-NL4
connectors. All four pins of both connectors are wired in parallel.
The E15-BX uses the pin assignments 1+/1. Pins 2+/2 are
designated to d&b C and E-Series active subwoofers. Using one
connector as the input, the second connector allows for direct
connection to additional loudspeakers.
The E15-BX 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 below.
The E15-BX is operated in parallel to a full range loudspeaker or
direct from the E9-CO and driven using pins 1+ and 1-, hence the
difference in the pin assignment to d&b active subwoofers.
