Electro Voice S-40 Ultracompact 5.25-inch Two-way Full-range LoudspeakerDelivering high performance in an ultra-compact package, the S series is ideal for both distributed and near-field applications requiring high-quality sound. The two-way short-throw system is housed in an optimally vented, high-impact polystyrene enclosure that is suited for installation both indoors and out. Lows are handled by a 5.25- inch direct-radiating woofer with a polypropylene cone, while the high-frequency section is a one-inch direct-radiating soft-dome tweeter that is ferrofluid cooled. Built-in automatic power limiting independently protects each driver from unsafe transients. With mounting options that are flexible enough for virtually any application, the S series is perfect for anything from background and foreground music in restaurants and clubs to near-field monitoring in control rooms and broadcast studios.
