Very compact and lightweight... yet deceptively powerful.

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.

    As reviewed by Franky Fingers on 1/11/2011

    I started using a pair of Sb122's for my sons digital kit with ZX1's on top and they rocked. When I purchased my first Sx300 and put it on top of the Sb122 as a compact PA, it kicked like the police coming thru the front door. I tend to cross these over around 90-100hz and run them wide open for the lows as a compact PA for small to med size rooms. Kick drum and bass guitar do well coming thru a pair of these. 1 is good,,,2 are great used as subs w/Sx300's poled up on top. Just remember that the Sb122 weighs in around 34 lbs and the Sx300 tips the scales around 31-32 lbs. 24-30 inches is plenty high to mount them to keep the set up stable. The good thing about Ev's is that you can drive them at their max RMS levels all day long with a massive amount of headroom and are still very clear and punchy,,,kinda like a couple of compact cannons. Easy to carry, easy to hook up, and a full PA system using 2 of these subs and 2 mains would fit into the back seat of most cars out there. Who would believe that you can walk into a gig with a sub in each hand? I (and my back) would like to thank Ev for providing a compact sub at a compact price that does the job just fine. I'd recommend these for bands, DJ's, or anyone that wants a compact sub that'll rock the house.
