Performance
Power. Depth. Adaptability.
The WS-12 Subwoofer is the most powerful studio subwoofer available under $1000. 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.

DSP Features

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’ 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.
With selectable crossovers every 20 Hz between 40 and 140 Hz, it can be easily matched to any system. Because of the 1000W power amp, it is capable of keeping up with very powerful studio monitors without breaking a sweat.
The WS-12 can be used for bass management in systems as large as 5.1 with nearfield studio monitors, and the WS-12 can even be configured as a dedicated Low Frequency Effects channel.
One WS-12 will be sufficient for use with suitcase-style all-in-one PAs like the Yamaha® StagePAS® or Fender® Passport® or linear array all-in-ones like the Bose® L1® or LD Systems® Maui®.
Two WS-12s can be used side by side for use with larger systems. With two subwoofers side by side, total system Max SPL is now 129 dB with frequency extension down to 23 Hz.
