RCF TTS 15-A Active 15-Inch Touring Subwoofer

The TTS 15-A is the compact bass module for RCF's TT+ touring systems. A 15-inch woofer on a 3-inch voice coil is driven by a switch-mode Class-D amplifier rated 1100 W RMS and 2200 W peak, covering 40 Hz to 400 Hz and reaching 134 dB at one meter. The point of the cabinet is deployability: it is light enough for two people and small enough that a pair fits under a stage lip.

Processing is on board, with selectable 40 or 50 Hz high-pass, a low-pass variable from 60 to 400 Hz, gain, EQ, presets and output delay, plus a fast limiter and thermal and RMS protection. RDNet over Ethercon puts all of it under laptop control alongside the tops. The Baltic birch cabinet has a steel grille, two side handles, two M20 fly points and an M20 pole thread, and mains loop through Powercon in and out.
