Read MoreDescription: The Atrium65SDI has a unique, patent-pending Dual Input/Single Input Switch. Combined with its ingenious Dual Tweeter Array, this switch allows the Atrium65SDI to be used either as a single high performance stereo loudspeaker, or the left-or-right speaker in a high performance stereo pair. And you can use it practically anywhere, because the Atrium65SDI also has special military spec waterproofing features, including a patent-pending waterproof Power Port bass vent. The Atrium65SDI has an innovative dual crossover network that is enabled or disengaged via the simple switch located over the Binding Post Connectors. It sums the complete stereo signal (Left AND Right) or the single Left OR Right signal and mixes the signal to the appropriate tweeter or tweeters for the best performance, smoothest blending and most detailed imaging of any multi-application speaker. For single speaker stereo performance where a pair of speakers is inconvenient, or as a pair of speakers where high performance, weather-resistant speakers are needed, listen to the Atrium65SDI. Unique Dual Input/Single Input Feature: A rear mounted switch allows the Atrium 65SDI to operate as a single, dual-input speaker for stereo applications, or a traditional single-input speaker for left or right use. 6-1/2 (16.5cm) long throw Polymer Cone driver with Butyl Rubber Suspension for superior bass and midrange response. Dual Voice Coil driver for stereo play. Two 1 (25mm) Dome Tweeters with Neodymium Magnets for Minimize |
