SB-2
Professional Series – Dual-Coil Subwoofer With Stereo Inputs
SPECSHEET
Frequency Response:
Measured with distance referenced to 1W total, 1m at
two-boundary junction (pi loading, dotted line) and at
three-boundary junction (pi/2 loading, solid line)
Impedance per SB-2 input
Impedance:
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 maintaining 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.
