Speaker Placement

The low frequency capability of the CSUB allows great flexibility in its placement.While full-range speakers will typically be installed throughout the ceiling in an evenly spread pattern, the CSUB can be placed wherever it is most convenient. This usually means where the subwoofers best meet the needs of the overall sound system, or may some- times mean where they best fit into the ceiling. This flexibility is useful in irregularly- shaped rooms or when the depth of the area behind the ceiling surface varies.

An important performance parameter to keep in mind is that the location of the sub- woofer will affect its output sound pressure level (SPL) within a room. Locating the CSUB close to a wall will increase its output by approximately 3 dB over locating it toward the center of the ceiling area.The 3 dB increase will effectively double the amount of output power coming from the subwoofer. Locating the CSUB in the corner of a room, adjacent to 2 perpendicular wall surfaces, will increase its output by 6 dB.This 6 dB increase effec- tively quadruples the output of the subwoofer compared with locating it closer to the center of the room. The tradeoff for this extra output is a less uniform overall sound level, especially in large rooms.

Three possible locations for a CSUB Subwoofer

within a larger sound system:

1

	Center of Ceiling: Optimum Bass Distribution
CSUB	Most Uniform Sound Level

3	2
Near Corner: + 6 dB Output	Near Wall: + 3 dB Output
CSUB	CSUB

Note:The CSUB may be placed as close as 5" from a wall, provided care is taken to ensure that mounting clamps are properly extended (see Installation section). If mount- ing clamps cannot be properly extended, another location must be found.
