АС потолочная круглая 3" 16W EXTRON SF 3CT LP (пара), 60-1311-03

The Extron SoundField® XD model SF 3CT LP is a 3” full-range ceiling speaker featuring a 4" (10.2 cm) deep composite back can for use in plenum rated ceiling environments. This low profile speaker is ideal for ceiling installations with tight above-the-ceiling space issues, such as air handling ducts installed close to the ceiling. With the AV industry's first UL 2043 listed composite speaker enclosure, the SF 3CT LP meets stringent UL requirements for smoke and heat release in plenum air spaces. A magnetically attached grille with a thin-edged bezel gives the SF 3CT LP a refined appearance on the ceiling. The SF 3CT LP offers both direct 8 ohm and 70/100 volt operation with a behind-the-grille, six position power selector switch. With 70/100 volt taps at 1, 2, 4, 8 and 16 watts, the SF 3CT LP will handle most distributed audio needs.
