SP 1800 loudspeaker 3 way Wired 50 W

50 W 3-way 2.0 channels. Number of drivers: 3 80 - 20000 Hz 8 Ω. Amplifier. White. 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.. Three-Way. 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.. Bass Reflex. 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.. Rugged Grille. A metal grille protects the drivers from physical interference.. Tough Finish. Constructed with tough ABS plastic, the finish withstands the rigors of the professional use.. Pro AV Applications. In small to medium presentation environments a wide dispersion is generally more important than microphone feedback management, so no horns are used.. Horizontal C bracket. The adjustable brackets allow the installer to easily angle up 30º or down 30º. Or leave the brackets off and use as shelf speakers.. Note: these are passive loudspeakers – there is no amplifier built in – so they need to be used with an external amplifier.. Loudspeakers. Woofer diameter (imperial). 13.3 cm (5.25").
