Designed for the studio or light-duty stage applications, the Kali Audio WS-12 is an active 12" subwoofer well suited for recording studios, broadcast environments, film mixing, and small stage setups. The WS-12 utilizes a 1000W Class-D amplifier to power the woofer, which is capable of a frequency response of 30 to 160 Hz at ±3 dB (23 Hz at -10 dB) and a maximum SPL of 123 dB.

The WS-12 excels at reproducing film soundtracks, as well as bass heavy music like EDM and Hip-Hop. The front-firing port tube is designed to ensure that all the air leaves the port tube at the same velocity, preventing turbulent chuffing while creating a tight, clean bass tone that is devoid of noise.

The rear panel offers several DIP switches for setting crossover settings, gain controls, and polarity. Two combo XLR-1/4" inputs and two XLR outputs allow for flexibility when deploying in the studio or onstage. Additionally, there are a pair of RCA inputs, which are defeatable via dip-switch settings. A universal power supply allows the WS-12 to be used anywhere in the world with the flip of a switch. The Kali Audio WS-12 ships with a power cord.
