The All-Terrain (AT) Series landscape speakers feature a coaxially mounted 1" aluminum dome tweeter design over a proprietary high-excursion 6" woofer. Our AT speakers come with a built-in crossover network and 100 Watt low-loss, toroidal 70 Volt transformers, allowing these outdoor speakers to play at higher volumes while still maintaining a smooth frequency response of 70-20kHz. The woofer features an aluminum cone and Santoprene™ surround to withstand harsh outdoor environments. The AT62-70 is constructed of aircraft aluminum and includes an aluminum perforated grille to provide years of trouble-free use.
