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.
