Active Beam Shaping, Self Powered, Column Loudspeaker Array, IP55 Rated. The Intellivox HP-DS170 is a self-contained, especially high-power and high-output, 2-way, wide-bandwidth beam-shaping powered column loudspeaker with a high degree of outdoor capability. Since beam shaping’s introduction in 1999 the Intellivox High Power models have been specified to solve the problems of speech intelligibility and musical reinforcement in large highly reverberant spaces including houses of worship, theaters, transportation halls and more. The Intellivox HP-DS170 is capable of delivering up to 106 dB SPL at 30 meters and has a horizontal dispersion of 100°. With an array length of 1.7 meters it is designed to fit unobtrusively into spaces with challenging architectural and acoustical factors. Enclosing ten, high efficiency, 6.5” loudspeakers and two coaxially mounted 1” compression drivers, each with dedicated amplification, the Intellivox HP-DS170 is capable of covering a substantial audience area while maintaining an even sound pressure level throughout.
