Application Notes:
Subwoofer Placement for Tonal Balance – The location of the subwoofer in relation to wall, floor or ceiling affects the
tonal balance of the system. In systems having two satellite speakers, proper balance of sound is usually best attained
by installing the subwoofer via its wall-mount bracket at the center of a wall (instead of mounting it at a 2-boundary
area such as a wall-floor junction). For systems with four satellite speakers – such as the Control 50PACK System –
mounting the subwoofer in the center of a wall produces good basic bass levels. Locating the subwoofer at a two-
boundary junction, such as a wall-floor or wall-wall junction, provides stronger bass. A corner location provides the
strongest bass for maximum bass impact. In addition to subwoofer placement, external electronics equalization such
as from tone controls or DSP can be utilized to adjust the tonal balance further.
Port Clearance – Do not block the port of the Control 50S/T subwoofer by mounting too close to a side wall. Leave a
minimum of 50 cm (2 feet) of clearance between the port and an adjacent wall surface.
Using Control 52 without Control 50S/T Subwoofer – The Control 52 can be damaged if driven with frequencies
below 140 Hz. The subwoofer provides the proper high-pass filter. For using Control 52 by itself (not driven from the
Control 50S/T’s satellite output), the signal must be high-passed, either via a passive high-pass built into another
subwoofer such as the JBL Control 40CS/T in-ceiling subwoofer, or via an electronic high-pass, electronic crossover, or
DSP (140 Hz, 24 dB/oct recommended). Failing to high-pass the Control 52 can result in damage to the speaker.
Wall Bracket Orientation – Install the wall bracket so that the subwoofer drops down into the bracket. The bracket
clicks into place. Do not install the bracket sideways or on a ceiling. See the Control 50S/T Installation Guide.
To remove the subwoofer, release clip by pushing clip toward the wall with a long screwdriver (or similar)
from the top side of bracket.
Secondary Safety Cable – When installing subwoofer,
always utilize a secondary safety cable attached to the
separate 6 mm insert located on the back/wall side
of the subwoofer.
