Ceiling Mount Speaker


The PC-688RC is a Ceiling Mount Speaker with integrated resin panel and speaker frame. It feature spring clamp mechanism for easy speaker mounting to ceiling. The slim speaker frame design allows it to blend into the interior design of the application easily. Input impedance can be easily adjusted by changing the tap of the transformer. PC-668RC, comes with input terminal block which makes cable connection easy when bridging wires.

The ceiling mount loudspeaker shall be an integrated dual cone driver, line transformer and baffle (grille) assembly. The driver shall be a 30cm (8") diameter cone type with 8 ohm nominal impedance and a ferrite magnet. Power handling shall be 15W (30W continuous program) with a frequency response from 65 – 20 KHz and sensitivity of 96 dB SPL at 1 W input measured at a distance of 1m. The line transformer shall accept 70V and 100V inputs with taps for 15 W, 10 W, 5W and 3 W. The baffle shall be made of polypropylene resin and grille shall be surface-treated steel plate net with a traffic-white color (RAL9016). The speaker shall have a capacitor mounted on the push-in connector which accept AWG 14 – 24 (Ø0.8mm – Ø1.6mm) cable size. The three-piece spring clamps on the baffle allow easily mounting to the ceiling. The speaker cone, connector and line transformer shall be protected by a dust cover.

The dimension of the speaker shall be Φ280mm x D 90mm and weight shall be 970g (2.14 Ib)

The ceiling mount loudspeaker shall be TOA model PC-668RC-AS.
