SUBWOOFER SETUP AND CONFIGURATION
All Series MX systems feature a dual subwoofer configuration. The subwoofers are deliberately orientated in an asymmetrical “up” and “down”
configuration that will help balance the in-room low frequency response.
It is possible to wire up the two subwoofer loudspeakers in the following ways:
Note - By wiring the subwoofers in parallel, the load impedance presented to the
amplifier is halved to 4 Ohms, which consequently demands double the output current
from the amplifier. Care should be taken to ensure that the specifications of the amplifier
explicitly allow the increased loading of 4 Ohms, especially when used in a bridged mono
configuration.
It is strongly recommended to run separate cabling for all channels in the MX modular
loudspeaker system back to the central amplifier rack to permit future flexibility with the
wiring configuration.

Each channel of a stereo power amplifier is
connected to each subwoofer separately.
Utilising a stereo power amplifier in
the bridged mono configuration, both
subwoofers are wired in parallel across a
single pair of output terminals. Check the
wiring and setup details in your amplifier
manual.
