The 1MN Planar Speaker can reach up to 100 yards in sound making it ideal for universities and college campuses, critical industrial or manufacturing facilities, recreation venues, air ground sea transportation centers, and public gathering spaces. The Clear Voice MN Series creates maximum vocal intelligibility and clarity, even while transmitting that message over very long distances. Designed specifically to meet the extraordinary acoustical and environmental demands of mass notifications, the Clear Voice MN systems are the first choice when long distance clarity and intelligibility are the priorities. This Planar speaker is effective for both mobile and fixed installations. Mobile MN speakers allow for rapid deployment on tripod stands or in emergency vehicles, boats, or aircraft.
