Product Details T820
T820 is a passive TORUS element for small and medium systems that do not require the longer throw of a line array. It primarily forms vertical constant-curvature arrays, but can operate alone as a point source. Horizontal centre clusters also suit short-throw rooms with high ceilings, such as some theatres.
The defined pattern is 100° horizontal × 20° vertical. Its compact size supports live sound, permanent installations, corporate events, musicians and DJs.
An 8-inch neodymium LF driver uses a front phase plug to raise mid-band sensitivity. Two 1-inch-exit neodymium HF drivers have 1.4-inch high-temperature polymer diaphragms, supporting consistent performance at higher output.
The plywood enclosure has textured paint, two recessed handles, pole-mount fittings and a full-width cloth-backed steel grille. Integral rigging and dedicated frames support approved horizontal or vertical arrays of up to six enclosures.
Two NL4 connectors use passive input pins 1+/1− or 2+/2−, selected by a rear switch. iKON amplifiers provide DSP, VU-NET control and Dante integration. A VU-NET-addressable LED identifies the cabinet circuit, while DISPLAY 3 models and optimises audience coverage.
SX subwoofers extend the bass response. SXCF115 is the specified mechanical partner for compatible flown or ground-stacked configurations. Standard finishes are black T820B or white T820W.
