Includes 2 Definitive Technology ProMonitor 800 Bookshelf Speakers. Bring Definitive Technologys legendary speaker technology to an infinite variety of environments with the ProMonitor 800. Boasting the heralded innovations and patented technologies of its much bigger brothers, the ProMonitor 800 is a versatile performer that fills any space with sensational sound, not with size. For slightly smaller spaces than big brother ProMonitor 1000, ProMonitor 800 features identical Definitive Technology top of the line innovations, including BDSS woofers, pure aluminum tweeters, and planar bass radiators. Use ProMonitor 800 as stereo pairs or satellites for any number of surround channels. Mix and match with other ProCinema models such as the PC1000 Center Channel Speaker. Put them everywhere and aim them anywhere using their built in stands, or choose optional wall mounts or floor stands. ProMonitor 800 utilizes the same aluminum tweeter material as our top floorstanding speakers. Aluminum is light and stiff, making it the ideal material for a driver that must move beyond 20,000 times per second to reproduce the highest frequencies we can hear. Youll hear clean, detailed highs that produce air and dimension in the room.
