SB122 12" 400W Passive Subwoofer

With the Electro-Voice SB122, the quest for a compact, lightweight, powerful, and affordable subwoofer is finally over. The SB122 is possibly the smallest, most powerful subwoofer on the planet. It packs 400-watt continuous-and 1,600-watt peak--power handling into a compact 33 lb. package. It also employs the new EVS12SB 12", long-excursion woofer for outstanding low-frequency response.

Aesthetically, the SB122 sports a half-face grille with grille cloth, and a stylized EV logo. The rich feature set includes a top-mounted pole cup, ergonomic carrying handle, large port, and a built-in low-pass filter that eliminates the need for external processing. Of course, external processing is still an option for professionals seeking greater overall system performance gains. And, with a price that makes it all seem too good to be true, SB122 is sure to make you rethink what a compact sub can be.

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 2" of peak-to-peak excursion capability, this is literally a 12" with the heart of an 18".

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 bi-amp applications without the need to disable the internal filter. For maximum output in bi-amp 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 compact system than sounds much bigger than it looks.
