Positioning
The CMS loudspeakers are near field monitoring loudspeakers and should be positioned at a distance between 40cm
and 3 meters from the listener, pointing towards the listening position. They can be sitting on the console top, hung
or even placed on appropriate stands. In any way, it is recommended that the tweeter is at a height from the floor
approximately equivalent to that of the listener's ears. If required, it can make sense to place the speakers upside
down so that the previous rule is better fulfilled.
The CMS loudspeakers could be placed vertically or horizontally depending on the environment, preferably pointing
towards the listener (fig. D, E, F).
Once the position is defined, you have 2 kinds of feet (4 rubber feet and 2 adjustable spikes) to optimize the louds-
peaker positioning (fig. G, H). The adjustment of the spike height permits to control the height of the soundstage.
The gap and the right/left positioning of each loudspeaker permit to control the width, the centering and the global
coherence of the soundstage (left/center/right), at the source of your recording precision.
Running in
As in all brand new loudspeaker, the drivers need some run-in period: the CMS transducers are mechanical elements
demanding a little time to settle and adapt to the climatic environment. This period will vary, depending on the working
conditions and may take up to a few weeks. Avoid pushing the speakers very hard during their first hours of use, but
to accelerate the run-in process, it is good practice to operate the speakers at moderate levels for 20 hours or so, with
programs having significant low frequency content. Only once the transducers have come to stabilize will you get the
optimum performance.
