Connect these Powered Wall-Mount Stereo Speakers from Amplivox to your multimedia or PA system to reach audiences of up to 500 people. Molded plastic enclosures protect these 30-watt speakers from scrapes and scratches. Each speaker box houses one 5-inch full-range speaker and one 1-inch dome speaker. An amplifier in one of the boxes powers both units. Connect your audio source using the RCA stereo input. Easy-to-use controls let you adjust your volume, bass and treble.
