The unconventional GEO SUB displays exceptional forward gain across three octaves eliminating many problems common to omni-directional LF. A high-efficiency, front- loaded 18" driver delivers 140-143dB Peak SPL, while twin 12" side-firing transducers help create cardioid LF pattern control via precise rear pattern cancellation.
NX242 TDcontrollers, fitted with the required NXtension Expander Boards, employ advanced digital filter sets with new, proprietary algorithms, to optimize phase and extend GEO SUB's cardioid LF control from midbass to subbass. The Over/Under GEOD-BUMPER allows as many as 16x GEO SUBs to be flown together and presents multiple stage-stackable options.
