CPS4212 type dichotomy frequency main speakers system

· Dichotomy frequency, two-way drive screen main channel movie speaker system
· Level covers Angle ±45 °, vertical covers Angle ±20 °
· low-distortion sound waves guide tube, to guarantee tone quality plump
· Installation is simple and convenient.

CPS4212 is perfect for big-scale and medium-sized digital stereo movie halls with 200~600 seat and projecting distance between 18m and 25m. 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, precision and phase inversion design and close coupling of the 2 units, which improves the sound output efficiency and enhances the frequency range. Treble system constants of PH2318 type small diameter and biradial horn with a directional invariance in it and PD2121 type high frequency drive, The drive unit adopts phase equilibrium network, which can make the horn and drive with flat frequency cohesion and stable working condition.
