Constant-Directivity Loudspeaker
APX40TN
APX40TN
Conservatively rated 40 watts, constant-directivity paging loudspeaker for use in public address or paging appli-
cations. Environment-resistant units feature a 60˚ x 40˚ (±10˚) constant-dispersion pattern across the controlled frequency
band of 1.25 kHz –10 kHz. The rotating bell pivots in precise 15° increments for exact on-site positioning of projection
angles. A triple lock security mounting method saves installation time and provides long-term stability. APX models are
equipped with an internal 25V / 70.7V / 100V transformer with screw terminal connections made beneath the rear cap.
Rear cap will facilitate armored cable. Power stripe code around the driver assembly provides identification of power rating
from a distance. Loudspeaker mounts to die-cast zinc base. Pre-mount the base to a standard 1-gang, 2-gang, or 4" square
E.O. box. If replacing
speakers, simply remove the APX base and mount to the Omni-Purpose
AP Series
neutral. Optional Replacement Bracket, APXBK-N, is also available.
