Kali Audio WS-12 12" Powered Subwoofer - Single

12" active subwoofer with 12" low-frequency driver, low-noise port tube, selectable crossover, gain adjustment, polarity reverse, and footswitch jack
MFR# WS-12

Product Description

The Kali Audio WS-12 is an affordable 1000W powered 12” subwoofer for studio or stage use. Its low-end is controlled by an easy-to-use DSP section to tune the proper settings needed for any system. The WS-12 is a great companion for near-field and far-field monitors, as well as PA systems. With frequency extension down to 23 Hz and 123 dB max SPL, you’ll have plenty of low end for any setting.

1000W of Class D power drives the WS-12. It’s capable of playing a bass management role in a 5.1 system, particularly when used alongside Kali IN-8 monitors. The WS-12 is also a great live subwoofer. The Kali Audio team designed the WS-12 to fit nicely into small vehicles. It’s size, enclosure, and carrying handles make transport between gigs easy.

The DSP section has various settings to optimize performance in any setup. The back panel includes parameters for selectable crossovers, gain adjustment, and polarity. To listen to a mix full-range, the WS-12 accepts input from a footswitch of your choice.


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

This sub is a sleeper for sure. The sound is massive. Size of the unit is manageable. The integration with the rest of the Kali family is flawless. Definitely, more than, worth the money. It punches well above its weight class.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
Phil T.
The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
