The Sb121 combines the advantages of a long-throw 12-inch woofer with a lightweight, yet strong polypropylene enclosure. The large vent centered on the top of the front helps the woofer move more air. The EV Sb12 woofer was developed specially for the Sb121 and has a specially designed deep frame geometry. At the heart of this driver is a magnetic structure optimized to yield the best possible combination of performance and output capable in this enclosure size. Its Kevlar composite cone and special surround give it nearly 2 inches of total excursion capability. The Sb121 should be used in conjunction with an active crossover with a minimum roll-off rate of 12-dB-per-octave to filter response above 200 Hz. It is also sensible to optimize the Sb121's output and protect it by using a subsonic filter at 40 Hz in the signal chain. The optional Electro-Voice AC-One loudspeaker controller provides easy adjustments for crossover filtering, variable subsonic filtering, a flexible 3-band EQ and LPN processing for added bass impact. The Sb121 can handle 300 Watts continuous, 1,200 Watts peak and can be safely used with amplifiers in that power range, as long as they are not driven to clipping. Using 1/2 or 1/4-space loading as well as mutually coupling multiple Sb121's give this small box very impressive output capability. The Sb121's parallel Neutrik Speakon connectors allow loss-free signal connection. The enclosure can be stacked, stand-mounted and safely suspended using a variety of flexible,inexpensive optional hanging kits (See our Suspending System 200 Loudspeakers manual for more details). The Sb121 is a truly professional highperformance woofer system. Technical Specifications: Freq.
