Each cabinet delivers up to 1500 W RMS (3000 W peak) and 136 dB max SPL, driven by a robust neodymium motor with a 4.5-inch voice coil for fast, accurate transient response. Onboard SysCore DSP provides advanced limiting with temperature and voltage monitoring for rock-solid reliability, plus a 4-band parametric EQ, six application presets (including low-latency and cardioid modes), and adjustable delay up to 50 metres. Connectivity is straightforward with 2 x XLR inputs and 2 x XLR thru outputs, while PowerCON loop-through streamlines power distribution.
