The Electro-Voice EVF-1181S-BLK is a passive 18-inch subwoofer from EV's EVF series. It handles 400 W.

A dedicated subwoofer transforms a two-speaker rig; the tops stop straining for bass and the whole system gains headroom. It is designed to pair with matching EVF full-range tops over a pole mount for a clean, cable-tidy stack. The EVF platform serves full-size permanent sound reinforcement.

The cabinet is braced 15 mm plywood under EVs EVCoat finish, which shrugs off load-in scrapes far better than painted MDF. Rigging is handled: threaded M10 points for eyebolts, aluminum pole mounts, and all-metal handles for daily transport.
