The Electro-Voice SB122 Compact 12-Inch Subwoofer is a very compact, lightweight sub woofer system that is designed to add bass enhancement to EV Sx and Zx Series speaker systems running on 70.7V or 100V distributed lines.

The full face weatherized stainless steel grill with hydrophobic cloth inhibits water from entering the port or coming into contact with the woofer. The SB122PIX 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 SB122PIX 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 SB122PIX 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 SB122PIX to be used as an independent sub woofer in bi amp applications without the need to disable the internal filter. For maximum output and protection of the driving amplifier against transformer saturation at very low frequencies, a Butterworth 24 dB/octave high pass filter tuned to 50 Hz is recommended.
