Electro-Voice EVF-1151S-PIB Subwoofer, Single 15" 400W

Bring powerful, intelligible low end to outdoor and installed systems with the Electro-Voice EVF-1151S-PIB pro subwoofer. This single 15" weatherized subwoofer is built for professionals who need reliable low-frequency reinforcement in exposed environments — delivering 400W RMS and a useful 44 Hz–174 Hz response that tightens bass and improves speech and music clarity across large venues.

Designed around the EVS15SB woofer and advanced FEA-optimized motor and suspension, the EVF-1151S-PIB produces high SPL with low distortion and 99 dB sensitivity, reducing amplifier load while preserving headroom. The fiberglass-coated birch enclosure and gland-nutted input panel make outdoor PA, security audio, surveillance monitoring, and fixed-install deployments simple and durable. Installers benefit from flexible rigging options that let you combine EVF and EVH series cabinets for custom arrays, while phoenix-style connectors and an optional 70.7/100V transformer kit simplify distributed-sound applications.

Ideal for outdoor venues, stadiums, houses of worship, and security/monitoring systems — contact us to spec the EVF-1151S-PIB into your next pro audio or security installation.
