The Series MX systems are designed for
dedicated home cinema rooms, rather than
open plan living spaces. They are capable
of delivering sound pressure levels (SPL)
equivalent to commercial cinemas and
therefore are best installed in an enclosed
room to avoid disturbing other occupants of
the home.
Ambient light levels in the room should
be fully controlled to maintain the best
image contrast, as these speaker systems
are intended to be used with a projector in
conjunction with an acoustically transparent
screen. This is best achieved in an enclosed
space with no windows or openings to other
living spaces.
Room ratios are important. A rectangular
room is usually the most suitable shape
for a home cinema with the main speakers
ROOM SUITABILITY
firing down the length of the room. The slim
design of the Series MX main speaker and
subwoofer modules minimise the space
required behind the screen and maximise the
viewing distance in the home cinema (see
section 5 - front wall construction for more
details).
Due to the capability of higher SPL's than
typical home entertainment systems, it is
recommended that allowances are made in
the room design and construction for sound
proofing or isolation.
Sound isolation is
generally required to reduce or eliminate:
•
extraneous noises (eg traffic noise from
the street outside or internal plumbing)
entering the home cinema and disturbing
the soft passages of the film or music.
•
excessive
noise
(particularly
frequencies) emanating from the home

cinema and disturbing other members of
the household or neighbours.
Sound proofing a room for home cinema
use is best achieved during the construction
phase of the building. It is also possible
to retrofit an existing space with some
additional effort. Attention should be paid
to the thickness and density of the building
materials that form the boundaries of the
room (walls, ceiling and floor as applicable).
Focusing on all the openings in the room,
door seals, windows and air conditioning
vents can greatly increase the effectiveness
of room isolation at a moderate expense.
It is best to work with an acoustic consultant
to determine the level of sound proofing
required to best suit your situation.
