The X310 CARDIOID is a self-powered 3-channel high-end cardioid subwoofer, which features 3 x 10″ ported woofers and unique software controllable cardioid radiation pattern. The power output of 1500 W (RMS) ensures for very high SPL down to a frequency of 60 Hz. 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 definition is the most comprehensive and powerful loudspeaker management system on the market. It is seamlessly constructed into the software, cabling and connection concept. The cabinet can be used as a cardioid extension or normal LF extension for the X310. It shares the same outer dimensions and flyware and can be own together with the X310 as one line like conventional LF extensions or flown behind the X310 with the cardoid flying frame to set up a beamforming cardoid line array system. Due to the fully integrated connection hardware, the subwoofer can be stacked to realize larger systems with up to 10 meters of acoustic length. Internally, one X310 CARDIOID has 3 amplifier and 3 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.
