The X115 is a self-powered 2-way high-end cardioid subwoofer, which features 1 x 15″ ported woofer at the front and 1 x 12″ ported woofer at the rear side. The power output of 4000 W (RMS) ensures for very high SPL down to a frequency of 35 Hz. The subwoofer features a unique software controllable cardioid radiation pattern. The cardioid disperson avoids unwanted energy behind the system and reduces the reveberant field at low frequencies while providing highest accuracy in low frequency sound emission. The combination of mapping optimization and direct cardioid radition pattern denition is the most comprehensive and powerful loudspeaker management system on the market. The X115 can be combined with all products of the CADAC beam forming range. It can be used as ground stack horizontal subwoofer array as well as flown together with the X310 or X606 system in large venues for very high SPL demands in concert applications. Internally, one X115 has 2 amplifier and 2 DSP channels. The CADAC DSP-core module platform is integrated with the amplifier section into the loudspeaker. Cabinets are electrically connected by the CADAC C-Link audio and command interface. The CCP control and prediction software can connect to the array via LAN for command and control, Auto- EQ and to calculate sound prediction on listener areas. With the CMAP (mapping optimization mode), the vertical dispersion can be adjusted and optimized according to the listener area. Due to the fully integrated connection hardware, the subwoofer can be arrayed to realize larger systems with up to 7.2 meters of acoustic length.
