The Extron SoundField XD model SF 26CT LP is a low profile 6.5-inch two-way ceiling speaker featuring a 4.2-inch (107 mm) deep composite back can for use in restricted height plenum environments. The driver complement includes a 6.5-inch (165 mm) woofer coupled to a 3/4-inch (19 mm) ferrofluid-cooled dome tweeter. The SF 26CT LP offers both direct 8 ohm and 70/100 volt operation with a behind-the-grille, six position power selector switch. With high impedance taps at 8, 16, 32, and 64 watts, the SF 26CT LP is ideal for applications that require a high power distributed speaker system in plenum spaces that will not accommodate a taller back can. The SF 26CT LP provides a wide and smooth frequency range of 85 Hz to 20 kHz and is engineered with a 95 degrees conical dispersion that ensures excellent on and off axis voice intelligibility. A power rating of 130 watts continuous program also gives this speaker plenty of headroom for music reproduction in moderate to high output systems. The
