Speaker Options
Single Speaker Solutions
Lightspeed's flat-panel speakers produce a very wide dispersion of
sound, resulting in excellent distribution throughout the entire
classroom from a single speaker. Installation is very simple and
speech intelligibility is superb.
Traditional Speaker Solutions
For larger or multimedia classroom applications, we offer a line of
traditional speakers, which places multiple speakers around the
classroom. These speaker solutions cover classrooms up to 1600 square
feet and will deliver a full range of sound.
