The HPR153i 3-way loudspeaker is a great choice when the warmth, clarity and projection of a horn loaded, cone midrange system is desired. The 15" driver and larger enclosure volume provide extension down to 36 Hz making the HPR153i well suited for reinforcement of music with lots of low frequency content. Mids are handled by a 6" cone driver that seamlessly covers the critical vocal region. A 1.4" (diaphragm) compression driver delivers brilliant top end response. The 600 watt (400 LF/100 MF/100 HF) power module includes a 100 Hz high-pass filter for use in subwoofer-equipped systems.
