CPS4220 is a superthin speaker perfect for the developing medium and small sized digital stereo movie halls with 100~ 200 seats and projecting distance between 12 m ~ 18m. The bass system is specially designed for the extension of digital movie low frequency response. It adopts the high efficiency and high sensitivity PW1502 low-pitch unit and 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 PH2322 type biradial horn with a directional invariance in it and PD2109 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
CPS4220C is a speaker system that sets up a built-in power prescaler in CPS4220.
