Measuring 150mm wide x 215mm deep x the standard 1m high (39.0? x 5.9? x 8.5?) and weighing 15kg (33lbs), the ID84 uses eight 4 inch drivers and an array of dome tweeters on a curved baffle in a light-weight aluminum cabinet with a rigid steel spine. The choice of dome tweeters over a conventional HF compression driver results in particularly low levels of distortion and contributes to a ‘hi-fi' performance that extends the ID84's suitability well beyond the traditional column speaker role of voice reproduction into music applications. The ID84 achieves a frequency range of 90Hz to 20kHz with a peak SPL of 136dB. The unique directivity switch on the rear panel enables instant switching of vertical HF dispersion, and cabinets can be linked ‘end-to-end' to create longer columns. Multiple rigging options and a comprehensive range of accessories make it easy to deploy the ID84 in a wide range of fixed installations and mobile applications. Also available in black, white and custom RAL colors, the hybrid TIS version (ID84-TIS) features the Speakon connectivity of the touring version with the cloth covered grille of the installation version.
