RCF PL 50 Ceiling Speaker

The PL 50 is a 6-inch dual-cone flush-mount ceiling speaker for paging and background music. Its internal transformer connects directly to a 100 V constant-voltage line with two power taps at 6 W and 3 W, which covers most zone designs without extra parts.

The two spring clamps mount it into a false ceiling without tools or additional brackets, which matters when the job is a hundred of them. Response is 100 Hz to 20 kHz at -10 dB with 150 degree coverage and 90 dB sensitivity. The 186 mm plastic frame weighs 1.1 lbs.
