Placement

Since the speaker installation is permanent and the furniture placement may not be, the user

should first determine the best long-term location — one that will accommodate future relocation

of the furniture in the room, while still allowing for an unobstructed sound path from the speakers

to the listening area.

Within reason, wherever the speakers look

right is where they’ll sound right. For best

results, place the speakers 6 to 10 feet

(1.8–3.3m) apart, so they form a triangle

with the main listening area. Try to keep the

speakers at least 12 to 18 inches (30–45cm)

from the nearest reflective surface (side

walls or ceiling). When used near a televi-

sion, the speakers should be mounted a

minimum of 6 inches (150mm) from the TV

to avoid interference with the picture. 

As a final check on the suitability of the

mounting location, it’s a good idea to 

temporarily place a pair of small box speak-

ers, if available, at the mounting locations

chosen for the system. This will give the 

listener an approximate idea of what the

speakers will sound like in that location.

Listen for pleasing stereo image, realistic

stage height, or balanced surround-field

coverage (if using the speakers as rear-

channel surrounds). Note if any objects 

in the room impede the sound path from

the speakers to the listening area.
