The new Electro-Voice SB2A powered 12-inch subwoofer eliminates the need 
for external system processing and amplification, addressing the demand for 
lightweight high performance portable sound systems. 

Featuring dual 350 watt amplifiers, the SB2A’s switch-able powered speaker 
output can drive either an external 8 ohm passive subwoofer or full range 
loudspeaker. This makes SB2A a supremely versatile and compact “sub system 
drive” solution, easily configured with a variety of loudspeakers for a multitude of 
sound reinforcement applications. 

Typical SB2A-powered Electro-Voice system setups include: with a ZX1-90, 
as a standalone PA that fits in the front seat of your car; in clusters with Sx100 
or Sx300’s; with a passive SB122, for portable lightweight sub extension to 
replace bulky 15-inch two-way systems (two 16kg packages vs. one 40kg 
package); with an additional powered top box (such as the ). The 
possibilities are endless!

The SB2A shares the same durable injection-molded enclosure as EV’s popular 
passive SB122 subwoofer. Both utilize the EVS12S woofer, designed from the 
ground up for optimized performance within this small footprint enclosure.
