The Electro-Voice® SB122 bass module is a very
compact, lightweight subwoofer system that is designed
to add bass enhancement to EV Sx and Zx Series
speaker systems. The SB122 combines the advantages
of a long-throw 12" woofer with a strong, lightweight
composite enclosure. The large vent provides less vent
compression and turbulence for increased low frequency
output. The EVS12SB cast frame transducer created for
the SB122 uses the same motor and suspension design
as the EVS18S used in EV’s larger systems. With
nearly two inches of peak-to-peak excursion capability,
this is literally a twelve inch with the heart of an eighteen.
An integral low-pass filter allows the SB122 to be directly
connected in parallel with a full-range speaker for truly
impressive low-end output without the need for an

additional amplifier and processor. The filter is transparent
below 160Hz, allowing the SB122 to be used as an
independent subwoofer in biamp applications without the
need to disable the internal filter. For maximum output in
biamp applications and protection of the full-range system
when running in parallel, a 40Hz Hi-pass (subsonic) filter
is recommended. The SB122 features a convenient pole
mount socket on top of the enclosure to allow a small full-
range speaker such as the Zx1 or Sx80 to be mounted on
the optional ASP-1 accessory pole, resulting in a
