Vision's SP-1800 professional wall mounted loudspeakers are super-easy to install, look beautiful, and produce rich and powerful sound. They are 240mm tall and use a 5.25 inch woofer - the most popular size for classroom, meeting room, and boardroom applications. These loudspeakers use three drivers; a woofer, a squawker, and a tweeter. Asking a driver to produce a wide range of frequencies is always a compromise, so dividing the sonic range into three means each driver has a narrower range of frequencies to produce, resulting in less distortion and clearer sound. A bass reflex port allows greater excursion of the woofer, allowing the woofer to produce lower frequencies, and the phase-delayed movement of air from behind the woofer to the front reinforces the bass even more.
