experience has shown that the size of the
room and therefore the listening distance
from the speakers, plays a significant part in
determining the ideal speaker system.
Commercial cinemas are normally designed
and calibrated to produce "reference level"

further away from the screen and speakers
than in a typical living room. Therefore, the
sensitivity of the speakers and the power
output of the amplifiers need to be carefully
considered if the desired Dolby® reference
level is to be achieved.
The Series MX loudspeaker systems have
been designed to suit a range of room sizes
historically
to best deliver a true cinematic experience.
Taking into account the average number of
seats each room size can accommodate, the
table below illustrates the ideal room size
range for each Series MX screen speaker

the SPL in the back row of seats will be lower
than expected and clarity, intelligibility and
the overall impact of the movie sound track
will be significantly diminished.
