18-inch Front-loaded Subwoofer
The Electro-Voice EVF is the most comprehensive series of front-loaded loudspeaker systems ever offered for installed sound. Available in 12" or 15" two-way configurations, and enhanced with dedicated low-frequency systems, EVF1181S loudspeakers match exceptional audio performance, efficiency, ease-of-use, and aesthetics with unprecedented value. EVF systems incorporate the latest Electro-Voice components to ensure years of reliable use and consistently excellent sound. "S" designated systems are equipped with SMX series symmetric drive woofers and ND2B 2-inch titanium compression drivers; "D" designated systems are equipped with our highest performance DVX series symmetric drive woofers and the DH7N 3" pure titanium compression driver.

The EVF 1181S two-way full-range systems are offered in seven coverage patterns that provide solutions for the widest possible range of installation challenges. The 12" Constant Directivity waveguides can be rotated to work with a vertical or horizontal orientation. Bi-amp operation is supported, but the sophisticated fourth-order crossover and protection network makes cost-saving, passive operation extremely attractive. Using optional rigging accessories, you can create attractive clusters that include EVF full-range systems, as well as EVF subwoofers or EVH full-range systems. Cabinets are available in three finishes: EVCoat (interior use), PI (indirect weather exposure), and FG fiberglass - for direct weather exposure; they include twenty-two M10 threaded suspension points.
