F12/F15 Full-range with add-on S15/S18 sub-bass
The F12 or F15 can be used with either the S15 or S18 in passive add-on
mode. This provides a simple way of increasing bass performance without
the need for an additional amplifier. The switch at the back of the sub-bass
enclosure should be switched to "passive" and a link lead run from the sub-
bass to the F12 or F15. This configuration will present a 4 ohm load to the
amplifier. An M3 controller for this passive configuration is optional – just
performing limiting functions without any additional system EQ.
