Yamaha NS-333 2-Way Bass Reflex Bookshelf Speakers (Pair)

Two Way Bass Reflex Bookshelf Speaker SystemYamaha's NS-333 speaker system has been designed specifically for home theater applications. The bookshelf speaker is a bass-reflex design that can be used for main or surround channels and incorporates a 5" Polymer-Injected Mica Diaphragm (PMD) cone woofer and a 1" aluminum dome tweeter. For improved imaging, the tweeter utilizes Yamaha's exclusive waveguide horn. Waveguide HornUnlike most homes, movie theaters use sound absorbing materials on walls and ceilings. The result is that the sound reaching your ears is the sound wave produced by the speakers rather than reflected off the walls. Yamaha has created wave guides that greatly reduce reflected sound and increase the proportion of directly generated sound waves reaching your ears. The result is a clear and precise sense of sound direction and placement.
