The RL 180 NT EVAC is a EN 54-24 certified 2-way speaker that is designed to be suspended from ceilings in rooms with long reverberation times. The proven Polar® technology produces a consistently wide dispersion angle at medium and high frequencies. The cardioid pattern effectively suppresses disruptive sound reflections from the ceiling by minimizing the amount of sound emitted backwards at low frequencies.

As such, a small number of RL 180 NT EVAC speakers can be used to transmit speech very evenly and clearly, even in acoustically challenging rooms.
