Kali Audio WS-12 Powered Subwoofer

The WS-12 is a studio subwoofer to match your Kali Audio monitors -- plus, it pulls double duty as a 1000-watt PA sub for your portable live sound or DJ rig.

The WS-12 is a 1000W powered subwoofer for the studio and the stage. With frequency extension down to 23 Hz and 123 dB max SPL, it provides authoritative low end in any setting. It is made to be used with any near- or mid-field studio monitors, as well as with small portable PA systems in a live setting.

One of the key design specifications for the WS-12 is that it be capable of providing bass management in a 5.1 system where all of the full-range speakers are Kali IN-8s. As such, the WS-12 is powered by a 1000W power amplifier mated to a high-excursion 12-Inch driver.

This much power also makes the WS-12 a capable live subwoofer. Its enclosure is 18mm plywood and it has handles for easy carrying. Kali's team made sure that it will fit in small passenger cars, so you can take it with you even when you're calling a ride to get to your gig!

All this power is controlled by a robust, user-friendly DSP section that let you dial in the exact settings you need for your system. Whether you're using it with a pair of LP-6s, as bass management in a 5.1 system, or on stage with a PA, it's easy to configure the WS-12 to get exactly what you need. The WS-12 was designed as a companion subwoofer for Kali's LP- and IN-Series Studio monitors.

When used with a pair of Kali monitors, the subwoofer's crossover and gain settings can be configured to precisely match those of the full-range monitors. With these settings dialed in, set the subwoofer between the speakers, and turn all speakers' read more volume knob either to noon or all the way up. The subwoofer's level will be exactly where it needs to in order to match the full- range speakers. The WS-12 can be used for bass management in systems as large as 5.1 with any Kali monitors.

Convenient settings allow the use of an external crossover, and the WS-12 can even be configured as a dedicated Low Frequency Effects channel.


- The WS-12 has selectable crossovers every 20 Hz between 40 Hz and 140 Hz.
- 6 dB steps allow easy adjustment between free space, against walls, or in corners.
- Reverse the sub's polarity for better phase response in your system.
- Bypass the sub at the press of a button to listen to your mix on full-range speakers. When bypassed, the sub turns off, and output signal is no longer high-passed.

"Great Sub"

Overall: 5 out of 5 stars
(see rating details)
I have been mixing on my Mackie MR5 mk2 for over 5 years now and I have been having problems with monitoring my lows. I spent a lot of time on the internet looking for a 12 inch sub that is reasonably priced but all the ones I could find were way beyond my budget. I watched a review by Warren Huart on the Kali WS-12 and I knew that I had to grab one. I bought one, hooked it up with my MR5 at 80hz crossover point and my oh my, It sounded amazing! I am hearing deep lows like never before. I like the build quality and the dip switches are very easy to use. Thanks to the boys at Kali Audio, now my mixes sounds much better.
