21" Subterranean Subwoofer (4 ohm)
The 211ST 21" subterranean subwoofer was developed for high SPL bass output outdoor applications. It features a powerful 21" transducer for maximum excursion and SPL. Due to the high-power handling of the 211ST, no 70V version is offered.
At the 4 Ohm rating wire loss needs to be considered and calculated as with any other 4 Ohm wire run. Also, the 211ST is quite heavy. Four eyebolts are located on the top to allow the subwoofer to be lowered into the ground.
