Product Description
This is where DSP precision changes everything. APBMW X4E coaxials, APBMW S8-4 underseat woofers, and an APBX 10 S4S passive boot subwoofer are powered and tuned by the Audison Forza AF M8.14bit DSP amplifier. Using advanced EQ, crossovers, and time alignment, the system is optimised for the unique acoustics of your BMW. The Forza DRC AC remote gives instant control of bass level and preset switching from the driver’s seat.
