IS 122 LOUDSPEAKER 12” TWO-WAY INSTALLED LOUDSPEAKER
KEY FEATURES 2-way system with 1“ high frequency driver and 12“ woofer Selection of 80x50 or 50x40 rotatable horns Exceptional pattern control using Mathematically Modeled Dispersion™ Single loudspeaker design with interchangeable backplate options Full range passive crossover backplate Direct wire backplate for biamplification K8 compatible, actively tuned, self-powered backplate Single cable digital audio distribution, monitoring and remote control when used with K8 Simple and light weight array rigging accessories
PRODUCT DESCRIPTION The IS twelve two (122) series of loudspeakers are specifically designed for providing reinforcement in fixed installations where high sonic performance and flexibility in precise pattern control are critical. Precision designed with Mathematically Modeled Dispersion™ the twelve two series provides exceptionally linear pattern control through crossover making the series perfect for critical applications. Self powered versions used in conjunction with Klein+Hummel K8 products provide a factory tuned and easily-managed reinforcement system for night clubs, auditoriums, houses of worship, performance halls, arenas and stadiums.

ARCHITECT & ENGINEERING SPECS The sound reinforcement loudspeaker system shall utilize a 12” low frequency driver with 4” voice coil and 1“ high frequency driver. The loudspeaker shall provide at least 97 dB sound pressure level at a distance of 1 meter when driven with 1 Watt. The maximum peak sound pressure level shall be at least 132 dB. The coverage angle of the high frequency horn shall be 80 degrees horizontal x 50 degrees vertical, field rotatable or 50 degrees horizontal x 40 degrees vertical, field rotatable and shall be desingned using Mathematically Modeled Dispersion™ technology. The backplate shall be modular and externally removable with options for direct drive through Neutrik NL4 connectors, passive crossover electronics with Neutrik NL4 connectors or an active amplified backplate, all field installable. The frequency response shall be usable in an equalized system between 58 Hz and 22 kHz, +/- 3dB.
