DESCRIPTION The Community i2W8T loudspeaker is a two- way, fullrange loudspeaker system designed to provide high quality music and voice reproduction in applications requiring smooth, ultra-wide, horizontal coverage in 70V/100V applications. It provides an uncompromised musical system in a compact, attractive package. Engineered for use in underbalcony, downfill and distributed installations, the loudspeaker enclosure and faceplate are constructed of 13-ply Baltic birch; LF cones are of low mass, high stiffness carbon fiber; and the HF driver has a diaphragm of titanium. All drivers are Ferrofluid-cooled. The LF drivers and centrally placed ultra-wide 120º HF pattern control horn have been engineered to provide superior uniform pattern over the widest possible bandwidth. The unique “Super-V” configuration of the LF drivers provides exceptional uniform midrange pattern that would be impossible to create with a conventional flat wooden baffle plate. The multipurpose i2W8T is available in either a black or white painted finish, with a matching steel mounting yoke included for ease of installation. It is outfitted with a factory -installed 200W autoformer with taps at 200W, 100W, 50W and 25W.
1. Sensitivity: Free field pink noise measurement at 40 ft (12.2 m) at 65% power; extrapolated to 1 meter and an input of 2.83 volts RMS. 2. Watts: All wattage figures are calculated using the rated nominal impedance.

ARCHITECTURAL SPECIFICATIONS The loudspeaker shall be a two-way, full-range design with two 8" (205 mm) carbon fiber cone woofers with a centrally mounted 1" exit titanium diaphragm HF compression driver mounted to a pattern control horn. All components shall be connected to an integral crossover with a crossover frequency of 1.2 kHz. The input connection shall be a 5-terminal barrier strip. The loudspeaker enclosure shall be constructed of 13-ply Baltic birch with a perforated powdercoated steel grille and six integral M10 mounting points. The i2W8T shall meet the following performance criteria: amplitude response of 95 Hz to 15 kHz (+/-3dB), an input capacity of 200W (70V/100V), 96 dB SPL sensitivity (100 Hz - 12.5 kHz) at 1 meter with 1 watt applied. Nominal horn coverage pattern shall be 120° x 60° (H x V). Dimensions shall be 21.75 inches (552 mm) wide, 11.3 inches (287 mm) high, and 10.4 inches (264 mm) deep with a weight of 45 lbs (20 kg). Community strives to improve its products on a continual basis. Specifications are therefore subject to change without notice.
