The Yamaha NS-AW592 weatherproof outdoor speakers have a unique, appealing design that sets this system apart from other outdoor speakers, most of which are box-shaped. With a durable plastic cabinet and specially processed woofer and tweeter, these speakers will perform reliably when mounted outdoors. They are water resistant, and are not affected by sunlight (UV rays) or high or low temperatures. s. The woofer uses a highly responsive cone and a fluid-cooled soft dome tweeter, both specially processed for water resistance. The internal structure has been carefully designed for optimal time alignment between the two units, providing proper sound imaging. A waveguide and front baffle ensure good sound dispersion characteristics. The clarity in all frequency ranges is excellent, with very low distortion.
