A completely re-done version of the SB121, the SB122 is a true 12" subwoofer. We've also redesigned the box so that the stand socket is on the top, perfect for two ZX-1s to fly as satellites over the sub. That is a great coffee house system, or small extremely portable PA system. There is a band pass filter now in the SB122 so no external crossover is necessary, but you can still use one if you want to dial in the bass a little.
The Electro-Voice® Sb122 is a compact, lightweight subwoofer system that is designed to add bass enhancement to 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 is designed to move more air for increased low frequency output. The EVS12SB cast frame Transducer created for the Sb122 uses the same motor and suspension design as the EVS18SB used in EV's acclaimed Gladiator Sub. With nearly two inches of peak-to-peak excursion capability, this is literally a twelve-inch with the heart of an eighteen-inch. 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. Additionally, 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. 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 that sounds much bigger than it looks.
