Kali WS-12 12-inch (12") Studio Monitoring Powered Subwoofer
- 12-inch driver with a custom-designed amplifier delivers powerful and accurate low-frequency response.
- Built-in Class D amplifier provides efficient power delivery, ensuring clean and dynamic bass reproduction.
- Adjustable crossover and phase controls allow for seamless integration with your existing speakers and room acoustics.
- Robust cabinet construction minimizes unwanted vibrations and resonances, resulting in precise and focused bass reproduction.
- Versatile connectivity options including XLR, RCA, and TRS inputs offer easy integration with various audio sources and systems.
Enough output and bandwidth to tackle any situation
The WS-12 unveils every detail of your mix’s low end, all the way down to 23Hz at -10dB. This powered subwoofer tackles bass-heavy genres like EDM and hip-hop like a champ, and flawlessly reproduces the super-low-frequency content inherent in film soundtracks. Packing 1,000 watts, the WS-12 delivers impressive output — enough for a 5.1 array of LP-8 studio monitors. It’s even loud enough for light PA use! At Sweetwater, we appreciate the WS-12’s built-in limiter circuit, which protects the sub from unsafe voltage levels.
Versatile form factor and rock-solid build quality
The Kali Audio WS-12 is the perfect size. It fits easily under your desk — even in a small studio. What’s more, its mega-durable 18mm plywood enclosure and sturdy side handles make it roadworthy enough for live use. It’s also small enough to fit in most small passenger cars, so transportating it is child’s play.
Low-noise port tube exhibits clean, punchy low end
One of the WS-12’s most novel features is its low-noise port tube. Many port tubes emit turbulence, as air leaves the tube at different speeds from different points of the opening. This turbulence produces chuffing — a noisy sound that obscures the low-end details of your mix. The WS-12’s port tube, on the other hand, ensures that all of the air exits at the same velocity. The end result is clean, punchy bass with zero added noise.
Robust configuration options cover myriad applications
You can use the WS-12 in a myriad of applications, thanks to its robust configuration options. Its rear-panel dip switches provide you with selectable crossovers every 20Hz between 40Hz and 140Hz, along with presets for Kali’s LP-6, LP-8, and IN-8 studio monitors, plus LFE and external crossover settings. You can also select between four preset gain adjustment settings, reverse the subwoofer’s polarity, enable and disable its RCA inputs, and enable and disable its standby mode. To top it off, a rear-panel jack enables you to use a third-party footswitch to bypass the subwoofer — a must-have feature in the studio.
