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.
