Electro-Voice EVF-1181S-PIW Single 18-" 400 W Subwoofer, White

For installers and AV professionals who need dependable, room‑shaking low frequency without extra bulk, the Electro-Voice EVF-1181S-PIW pro subwoofer delivers professional-grade bass where it matters. This single 18" front-loaded subwoofer combines an EVS18SB transducer with FEA-optimized motor and suspension to produce deep, musical response down to 28 Hz while handling 400 W continuous power and delivering peak output up to 131 dB SPL. The rugged birch enclosure with EVCoat provides weather resistance for fixed installs, outdoor events, and security/monitoring command centers, while the versatile rigging design lets you cluster vertically or horizontally with other EVF/EVH modules to scale coverage. Integrators will appreciate the choice of a phoenix connector, NL4 options, and an optional 70.7/100V transformer for distributed systems — reducing onsite headaches and spare inventory. Ideal for houses of worship, performance venues, corporate AV, and surveillance audio monitoring rooms, the EVF-1181S balances power, clarity, and installation flexibility.
