The overhead music/paging speaker shall be a two-way bass-reflex enclosure type suitable for ceiling mounting. The low frequency component shall be a 4.72” (12 cm) cone-type speaker and the high frequency component shall be a 1” (2.5 cm) balanced-dome tweeter.
The speaker shall be compatible with low and high impedance speaker systems and include a built-in 25/70.7/100 V matching transformer. The front baffle shall have screwdriver-adjustable tap settings of: 6 W, 3 W, 1.5 W, 0.5 W, and 0.25 W for 70.7 V operation; 0.75 W, 0.4 W, 0.2 W, 0.06 W and 0.03 W for 25 V operation; and 6 W, 3 W, 1 W, and 0.5 W for 100 V operation; plus settings for 16 ohm and direct 8 ohm operation.
The output sound pressure level at a distance of 1 m with 1 W of input power applied shall be 89 dB SPL. The rated power handling (Continuous Program) shall be 18 W at 8 ohms, 12 W at 16 ohms, and 6 W when used with a 70.7, or 100 V line system. The speaker shall have a frequency response range from 80 Hz to 20k Hz. Speaker directivity shall be less than Q = 8 for all ISO 1/3-octave bands up to 4k Hz when measured in a half-space anechoic environment using 1/3-octave band-limited pink noise.
The speaker baffle shall be made of fire-resistant ABS resin. The grille shall be white painted steel plate with fire-resistant ABS resin trim and shall be field re-paintable. Instructions for re-painting the grille shall be included in the speaker package. The speaker shall be equipped with a spring-loaded push-in connector having two input terminals and two bridging pass-through terminals.
The speaker shall be no greater than 9.1” (230 mm) outside diameter shall require a circular cutout no greater than 8” (200 mm), and shall be capable of mounting in surfaces up to 1.46” (37 mm) thick. The rear of the speaker shall extend no more than 4.5” (113 mm) above the mounting plane. The speaker shall weigh no more than 3.31 lbs (1.5 kg).
The overhead music/paging speaker shall be TOA model F-2352SC.
