Placing Speakers for Surround Sound
For surround sound the minimum amount of speakers used will be five. Three at the front, FL (front left
channel) FR (front right channel) and C (centre channel) and two at the back, RL (rear left) and RR
(rear right). The front three speakers need to be on a level plane as possible with your ears whilst in your
seating position. This can either be achieved using in-wall speakers or the purpose built surround sound
ceiling speakers which have angled drive units that point directly down to your listening position. The
two rear speakers need to be placed left and right and directly behind your seating position, see Figure
1 on previous page.
Designing For Even Sound Distribution
When designing ceiling speaker systems in a multi-room environment, an important goal is uniform
sound coverage throughout the home. The goal should be to distribute the sound evenly in a way that
will not interfere with conversation and general day to day activities. In rooms where listening to music
isn't a primary objective (i.e back ground music) it is best to place the speakers around the perimeter of
room. It is especially important not to mount speakers above dinning tables or seating areas so that
people are not sitting directly under a speaker.
In locations where the primary objective is to listen to music the speakers can be placed evenly left and
right of the rooms main seating position as mentioned above.

Step 2 - Check For Obstructions:
If an obstruction is found behind the plasterboard in the proposed location, you will need to choose a
different location for the speaker. Before installing In-Wall or Ceiling speakers in pre-existing plaster-
board, check for joists or any other obstructions, such as metal pipes, which are hidden from your view.
Stud Locator:
The easiest, most efficient way to detect obstructions behind plasterboard is to use a stud finder. At
each proposed speaker location, use the stud locator to find an open space. Try to centre each
speaker between the joists. Slide the stud locator horizontally and vertically across the ceiling or walls to
locate the joists or any other obstructions.
Step 3 – Cut Speaker Openings:
1. At each speaker location, use the cardboard template to trace a cut line onto the ceiling or wall.
The Dimensions for the speaker, 229 x 229 x 145mm
2. At each location, drill a small hole in the plasterboard at the centre of the outline.
3. Bend a piece of stiff wire (e.g. coat hanger) about 6 inches from the end at a 90 – degree angle.
Insert the bent end into the hole and rotate the wire to check for any obstructions. If you hit anything,
patch the hole with plasterboard filler and choose a different installation location.
4. Using a fine – Plasterboard saw, carefully cut out each opening.
5. When finished cutting, remove plasterboard scrap from hole.
