RCF DU 31EN Two-Way Flush Mount Speaker

The DU 31EN is the speaker you specify when paging has to be intelligible and the ceiling has to stay tidy. A 4-inch woofer and a 1-inch dome tweeter cover 100 Hz to 17 kHz over a 180 degree pattern, and the on-board transformer connects straight to a 100 or 70 V constant-voltage line with tap settings of 8 W, 4 W and 2 W selected at the terminal block.

It is EN 54-24 certified for voice alarm, carries an IP 21C rating, and takes ceramic screw terminals in and out so a run can be daisy-chained without a junction box. Flush mounting is standard; the separate A 1331 rear cover turns it into a surface or wall speaker. RCF lists the DXT 3000, DXT 4000 and DXT 7000 as the matching amplifiers.
