DESCRIPTION The Community i2W8 loudspeaker is a two- way, full-range loudspeaker system designed to provide high quality music and voice reproduction in applications requiring smooth, ultra-wide, horizontal coverage. 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.
Weight: 41.8 lbs / 19 kg Shipping Weight: 49.5 lbs / 22.5 kg NOTES: 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.
The multipurpose i2W8 is available in either a black or white painted finish, with a matching steel mounting yoke included for ease of installation. It can also be ordered with or without a factory-installed 200W autoformer for 70V/100V applications (model i2W8T). Its six-sided, low profile enclosure and ultra-wide coverage pattern make the i2W8 ideal for use as a monitor, stage lip or side fill as well.
