Positioning Loudspeakers - Stereo

Never allow objects of furniture to impede the loudspeaker or place objects between the loudspeakers and

the listening position.

StereoPositioning

(P-38F / P-37F / P-17B)

The generally accepted norm is that

the loudspeakers should be as far

away from each other as they are

from the listener. This places the

listener and the loudspeakers at the

points of an equilateral triangle.

Well-designed horn loudspeakers

have “controlled directivity” - the dis-

persion pattern is tailored to provide

the ideal image at the listener’s ear.

This is in contrast to conventional

speakers, where the sound tends to

re o in all directions.

It follows that, when correctly sited, the performance of a well designed horn loudspeaker signicantly exceeds

that of conventional “direct radiator” loudspeakers.

Because the bass drivers are in a tuned port enclosure, the loudspeakers

must be operated away from walls and, specically, corners. The distances

in the above diagram should be considered as minimum distances. Placing

them too close to the walls will cause the bass to become bloated, muddy and

indistinct.

The angle at which the loudspeakers are placed relative to the rear wall is

called “toe-in”. Placing the loudspeakers with their backs parallel to the wall

will result in a poor stereo image with the so called ”hole in the wall” eect.

Angling the speakers inwardly too much will restrict the width of the listening

seat and also tend to narrow the stereo image.

In smaller rooms, it is better to place the loudspeakers more closely together

and set them relatively further back. This is preferable to placing the loud-

speakers further apart and sitting too close - the stereo eect will be signicantly degraded if you do.

The height of the loudspeaker is important. The midrange should appear to radiate from a point level with

the ears of a seated listener. As these loudspeakers are large, they will sound their best in large rooms, though

there are some adjustments that can be made to redress the position in smaller rooms. These will be discussed

in the section on nal positioning.

The above are our recommendations. Be prepared to experiment until the sound is exactly as you want!
