MSE-218 User Manual
v1.0 February 2013
3.0 - Cabling and Amplifier Selection
The MSE-218 subwoofer is designed to be used with professional power amplifiers providing the following
power outputs:
MSE-218 4000W/channel into two ohms
It is good practice to use an amplifier equal to the program power rating of the loudspeaker – so as to retain
sufficient headroom and good dynamic range. Care should be taken during operation to avoid amplifier
clipping – as this can cause serious damage to your loudspeakers. If in doubt, please contact your dealer who
will be happy to assist you in correct amplifier choice and setup. EM Acoustics recommends the EM Acoustics
AD-9 amplifier as the optimum solution for the MSE-218.
3.1 - Cabling
MSE-218 enclosures are supplied with Neutrik Speakon
TM
NL4 connectors wired pin 1+/1-.
Because the MSE-218 is a 2-ohm loudspeaker, cable insertion loss can become significant over long cable
runs. As such, it is recommended only that cables with a conductor cross-section area of 2.5mm
2
or greater
are used. The maximum cable lengths recommended for different conductor cross section areas are as
follows:
2.5mm
2
: 26 metres
4.0mm
2
: 43 metres
6.0mm

: 64 metres
A small power amplifier working too hard is more likely to damage a loudspeaker than a large power amplifier
working within its operating range!
