The Electro-Voice® SB2A dual channel powered

subwoofer is the ideal solution where big sound and

compact portability are required. Combining the amaz-

ing low-frequency performance of an Electro-Voice

SB122 passive subwoofer with dual high-efficiency

350 Watt amplifier channels and a dedicated electronic

crossover/processor, the SB2A eliminates the need for

a separate amplifier and crossover to drive a full-range

system. The second amplifier channel has a switch-

able high pass filter to allow either a passive full-range

system (Zx1, Sx300) or passive subwoofer (SB122) to

be connected via the Neutrik NL4 output. A line level

XLR output is also provided for daisy chaining to pow-

ered speakers or additional power amps. The SB2A

signal processing provides a carefully tuned overlap to

help round out the lower mids of the full-range system,

creating a big full sound from a very small package.

Like the SB122, the SB2A features a convenient pole

mount socket on top of the enclosure to allow a small

full-range speaker like the Zx1 or Sx80 to be mounted

on the optional ASP-1 accessory pole. The result is

a compact, self-contained 3-way bi-amp system that

sounds much bigger than it looks.
