General Description: Technical Specifications:
The Electro-Voice® SB2A dual channel powered
subwoofer is the ideal solution where big sound and
compact portability are required. Combining the amazing 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 switchable 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 powered 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.
