Want to take great Polk Audio speaker sound outdoors? Check out the indoor/outdoor 100-watt Atrium 55s. The all stainless steel and brass hardware is completely rustproof, as are the aluminum brackets that allow multiple mounting options and full 90-degree rotation: aim them to deliver the best possible sound in a variety of locations. The rustproof aluminum grilles have 55 percent open area for superior sound quality. Most importantly, the Atrium 55s rugged, weatherproof, design meets or exceeds several military specifications for water, wind, salt, and corrosion. Plus, the white finish is paintable so it can be matched to its surroundings. Inside the completely sealed enclosure is a 5.25-inch Dynamic Balance mineral-filled polymer driver with butyl rubber suspension for pumping out amazing bass, while its 1-inch soft dome tweeter with neodymium magnet broadly distributes high frequencies to cover a large area with high fidelity sound. Polk's Dynamic Balance technology produces flat frequency response, sharp detail, transparency and an ability to play program material with wide dynamic range at life-like volume levels without a hint of strain. The sound is always clean, clear, and effortless. The sculpted front baffle and rounded enclosure minimizes diffraction (sound reflecting off of hard edges) for more open and lifelike imaging. Connect them to an amplifier or receiver using the set's gold-plated five-way speaker-level binding posts. The Atrium 55s are also voice-matched to Polk's RTi speakers, and therefore make great surrounds in a complete Polk home theater system with the ability to handle up to 100 watts per channel... 5-1/4" woofer & 1" dome tweeter.
