MSE-218SP User Manual
v1.1 February 2013
5.0 – MSE-218 subwoofers in use
5.1 - System Overview
MSE-218SP subwoofers can be used either in landscape or portrait format, depending on
space requirements. Landscape format is recommended as the touring skids on the
underneath will protect the cabinet finish, and the stacking recesses can be used to add
extra stability when stacking multiple units.
5.2 – Stacking MSE-218SP Enclosures
The touring skids and stacking recesses (on the bottom and top of the enclosure
respectively) are intended to add extra stability to MSE-218SP stacks. Wherever possible,
the enclosures should be used in landscape format to use these skids and recesses, as the
skids will protect the paint finish. The placement of the skids allows the subwoofers to be
stacked with drive units facing either forwards or backwards to enable cardioid array
creation.
5.3 – Creating Cardioid Arrays
By assembling a stack of three MSE-218SP subwoofers, with the
central unit facing backwards, a cardoid subwoofer array can be
created which offers significant low frequency rejection to the
rear and sides of the array. When using the MSE-218 in this
way, the two front-firing subwoofers should be set into the
“normal” preset, and the rear-firing unit should be set into the
“cardioid” preset.
When using cardioid arrays, ensure at least 1 metre clearance is
left behind the array between the subwoofers and any walls or
other hard surfaces.
5.4 – Mounting fullrange products above the MSE-218SP
IMPORTANT SAFETY CONSIDERATIONS
Please pay careful attention when creating stacks of MSE-218SP subwoofers or mounting
fullrange products – either as stacks or using the M20 flange adapters. Ensure that the
instructions in this manual are followed correctly – MSE-218SP loudspeakers are heavy
and incorrect use could result in injury. Ensure that the floor where the system is going to
be placed is strong enough to withstand the total system weight placed upon it.
When assembling stacks of subwoofers, the use of ratchet straps to secure both the
subwoofers and any fullrange loudspeakers stacked above is strongly recommended to
reduce the risk of loudspeakers being shaken off the subwoofer and falling.
