4. Positioning

The position of speakers within the listening room is likely to have more

influence over their performance than any other aspect of their installation.

It is worth spending some time experimenting both with the finer points of

speaker positioning, as well as the larger scale issues of room layout.

If you are already familiar with the acoustic characteristics of your listening

room, and the way speakers perform in it, you may already have a good feel

for where to position your Linear Threes. However, installing any new hi-fi

component provides a good opportunity to review an existing set-up and

perhaps make improvements.

The position requirements for a pair of Linear Threes installed in an average

sized and furnished listening room (say 4m x 5m) are as follows:

•

Between 0.5 and 1.5 metres from the rear wall.

•

1.0 metres from side walls.

•

Between 2.5 and 3.5 metres apart.

•

Clear of corners.

•

Angled inward towards the listening position.

Don't worry if, thanks to the architecture or layout of your room, it is

not practical to follow each requirement. The most important thing is to

experiment with the different options that are practical and find the one that

works best.

While it is often the first instinct to position a pair of speakers against the

shorter wall of a rectangular room, it is often the case that a position against

the longer wall will produce better results. This is because the long wall

position tends to result in less prominent reflections from the side walls of the

room. However, whether used against the long or short wall, it is important

that each speaker of the pair is located in a similar

acoustic environment (different environments

would be, say, a curtained area and a solid wall).

The acoustic character of the side walls of the room

in the area where the main reflection between

speakers and listening position will occur should

also be similar. Diagram One illustrates a typical

layout.

Once your Linear Threes are connected (see Section

5) and working, and you begin to become familiar

with their performance, it is likely to be worthwhile

experimenting a little more with their positioning.

Reducing the distance between the speakers and

the rear wall will increase the level of bass and

low midrange making the speakers sound warmer.

The warmth however is likely to be gained at the

expense of some mid-range clarity and stereo image

focus and depth. Increasing the toe-in angle of the

speakers may regain some image focus but again

this is likely to be at a cost of image width and

openness. Learning through experimentation how

Linear Threes behave in your room will help you

find the optimum solution.

The Linear Three is magnetically shielded and can

be used in relatively close proximity to CRT screens.
