· Tri-dividing frequency, two-way drive screen main channel movie speaker system
· Level covers Angle ±45 °, vertical covers Angle: 20 ° (up) ~ 30°(down)
· low-distortion sound waves guide tube, to guarantee tone quality plump
· Installation is simple and convenient
· Projecting distance: 15m~20m
CPS4218 is perfect for medium-sized digital stereo movie halls with 100~300 seat and projecting distance between 15m and 20m. The bass system is specially designed for the extension of digital movie low frequency response. It adopts the high efficiency, high power PW1503 low-pitch unit and precision and phase inversion design, which improves the sound output efficiency and enhances the frequency range. Power frequency divider connects the medium and high frequency speakers. The drive unit adopts phase equilibrium network, which can make the horn and drive with flat frequency cohesion and stable working condition.
