The Apia C-Sub is a 12” powered subwoofer but also functions as a full-featured integrated audio system with internal DSP which forges a powered and processed output for creating a wide array of speaker configurations with the Apia Ciwi and Cimi series. The Cimi and Ciwi include a threaded mounting insert on the upper side of the speaker for attaching mid-high speakers. This makes the Cimi and Ciwi series convenient to use and ideal for medium throw applications in theaters, concert halls and audio/video installations in disco clubs, lounge bar, restaurants and shopping malls. All C-sub components are designed by Apia and custom-made under Apia’s exacting quality control.
