Electro-Voice's Sb121 Subwoofer is a compact, lightweight woofer system that is designed to add bass enhancement to EV Sx Series speaker systems. 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 drivers magnetic structure is 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. 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. 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. The Sb121 is a truly professional high performance subwoofer system.
