· low-distortion sound waves guide tube, to guarantee tone quality plump
· Installation is simple and convenient
· single-track cinema design
PS4208 is designed for single-track cinemas.It is perfect for big-scale and medium-sized digital stereo movie halls with about 100~150 seats and projecting distance within 15m. The bass system is specially designed for the extension of digital movie low frequency response. It adopts the high efficiency, high power PW1504 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 PH2315 type small calibre 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.
