The Sub 2.18 is a double 18"", high-power subwoofer for very high sound pressure levels: sensitivity 102 dB 1W / 1m, max. SPL 138 dB. Boasting power handling of 1000W continuous and 4000W peak, the Sub 2.18 can be used universally for active two-way or three-way systems. It is above all, however, the ideal companion to the C 25.2 for the creation of an active two-way system together with the DSP 260 or DSP 600 controllers and power amplifiers from the SL or LX series. For easier transport, the Sub 2.18 is prepared for the optionally available DC-WK-C18 wheel kit.
