SM8672 is a thin speaker system with a power prescaler built in. It is perfect for medium and small sized digital stereo movie halls with 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 PW1501 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 parts constants of PH2317 horn and PD2113 driver. The system’s high and low pitch units both are set in the direct radiation bass reflex. The drive unit adopts phase equilibrium network, which can make the horn and drive with flat frequency cohesion and stable working condition.
