18S/ST Indoor/Outdoor Subwoofer
The Control 18S can be connected into a system in a number of
configurations: In parallel with full-range speakers resulting in a
bass-overlap configuration (which is often acceptable); With an
electronic crossover and separate amplifier channel, or; Running a
full-range signal into the Control 18S and looping through the high-
passed satellite output to full-range speaker(s).
The optional Control 18ST version (and Control 18ST-WH in
white) includes a high quality multitap transformer designed
specifically for subwoofer use in either 70.7V or 100V distributed-
line systems. Multiple transformer taps at 60W, 30W and 15W (plus
7.5W at 70.7V) allow the Control 18ST to fit a wide variety of
listening situations. Taps are selected with a rotary switch
conveniently located on the back of the cabinet. The transformer
effectively limits the power to the speaker, so SonicGuard is not
included in the Control 18ST
Frequency response (1W,1 m) is measured on-axis with two
