Isolated from rear wall
Using
this
construction
objective is to de-couple the false wall and
speakers from the adjoining room wall. The
shelf studwork supporting the MX modules
is fixed securely with construction adhesive
in conjunction with screws or nails to the
baffle wall but is not directly connected to the
adjoining rear wall.
Vertical studs at the rear of the support
shelf should be secured to the floor, ceiling
and side walls. To reduce the incidence of
sound transmission, additional sheets of
plasterboard can be applied to the inside
face of the adjoining wall.
It is also strongly recommended that the
cavity created between the false wall and
adjoining room wall should be filled with bulk
fill insulation of a sufficient density to contact
the facia sheeting. This will avoid the storage
of vibrational energy both within the structure
and standing wave build-up within the void.
1. Erect a false wall frame adjacent to the
rear wall. Fix this wall to the floor and the
ceiling. (Figure 10)
•
Where possible, fill cavity with bulk
insulation and then line the frame with
plasterboard or other sheeting.
2. Erect a frame for the screen wall, and fix
this to the floor, ceiling and adjoining
walls. (Figure 11)
3. Fix noggins in between frames so that
plasterboard or engineered timber board
can be fixed. (Figure 12)
•
At this point it is recommended to insulate
the void around the speaker cavity as
much as possible using bulk insulation
or similar. The more material placed into
the cavity, the better for sound energy
absorption.
4. Finish the wall off using plasterboard
or timber board on the wall panels and
timber board on the cavity floor. (Figure 13)
•
It is important to use a timber board with a
minimum thickness of 16mm for the cavity
floor.
•
A hole for the speaker cabling is best
placed at the front corner of the cavity
floor.
