SB-2 Stereo Input Dual Coil Subwoofer
The Control SB-2 incorporates a long-excursion
250mm (10in) transducer providing usable output to
38 Hz. Dual voice coils on the transducer allow the
single cabinet to reproduce subwoofer frequencies
for both the left and right channels while maintain-
ing channel separation in the satellites.
Subwoofer placement can be used as a tool for
adjusting output sensitivity to match that of the
satellite speakers and the requirements of the
application. Positioning the SB-2 at the junction of
three boundaries (i.e. - at a floor/wall/wall or
ceiling/wall/wall junction) yields maximum output
sensitivity for use with high sensitivity satellites or
for subwoofer-heavy applications. Placement at
the junction of two boundaries (i.e. - floor/wall,
ceiling/wall or wall/wall) reduces the subwoofer
level by 3 dB. Placement in the middle of a single
boundary (i.e. - wall, floor or ceiling) further
reduces subwoofer output sensitivity by another
3 dB, to match with less efficient or higher
impedance satellite systems. The Control SB-2 is not
weather resistant and should not be used outdoors.
