Engineered for applications with limited plenum space incorporating a SoundTube-specific shallow backcan with an installed depth of 3.5 inches. One 5.25 inch (134 mm) polypropylene woofer with rubber surround and one 0.75 inch (19 mm) silk dome tweeter. BroadBeam Ring™ technology for mid-range clarity and smooth off axis performance. Easy-access six-position tap switch for 25/70.7/100-volt and transformer bypass settings allows for easy ordering, stocking and installation. Tuned port on baffle for added musicality and bass response down to 65 Hz (-10 dB). Reduced amplification costs and maximum efficiency of 84.5 dB sensitivity, 16 ohm impedance. Incorporates a painted steel grille for lasting durability. Adaptable to material thicknesses ranging from 0.035 inch (0.9 mm) to 1.6 inch (40.6 mm). UL 1480 and 2043 listed. Included accessories: Color-coded (orange) tile bridge, UL listed 0.5 inch conduit clamp, paint shield.
