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

Adding a subwoofer is the single biggest upgrade a portable rig can get: it takes bass duty away from the tops, so vocals clean up while the low end gets physical. 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.

Construction is braced 15 mm wood with the EVCoat finish EV uses across its touring gear; it is built to be loaded, not babied. M10 rigging points, a pole cup, and metal handles cover tripod, pole-over-sub, and flown deployments.
