About Your Subwoofer
Congratulations on your Kali Audio WS-12 Subwoofer! This subwoofer was designed to deliver accurate, authoritative low end for recording studios, and also to be used on stage in
light-duty applications. Whether you need to mix very low frequency content, or if you’re
just looking for some punch, you’ve picked an excellent subwoofer!
Where does “WS” come from?
The official name of this product line is “Project Watts.” Kali names all of our product lines
after towns in California. Watts is a neighborhood in Los Angeles that features prominently in the history of West Coast Hip-Hop. The name is also an allusion to the high power of
this subwoofer; capable of 1000W peaks, this subwoofer far outpowers other studio subwoofers in its price range.
Output and Bandwidth
The WS-12 is designed to provide enough output to serve as the subwoofer in a 5.1 setup
with 5x Kali Audio LP-8s. Having been designed for this demanding task, the WS-12 is easily capable of serving as the subwoofer in most stereo monitoring applications.
This high level of output also makes the subwoofer suitable for use alongside small portable PA systems. A single subwoofer may be used alongside PA speakers with similar Max
SPL specs in small settings. In larger settings, two subwoofers may be used side by side.
The WS-12 plays down to 23Hz at -10dB. This is low enough to reveal details in very low
frequencies in film soundtracks, as well as bass-heavy music like EDM and Hip-Hop. This
bandwidth also makes the WS-12 an excellent choice for live playback of these genres.
The WS-12 is equipped with a limiter circuit that will protect the subwoofer from unsafe
voltage levels. This will be plainly audible as distortion, indicating that the speaker is receiving too much input signal. If this is the case, it is recommended to reduce the volume
of the playback material.

About Your Subwoofer
Form Factor and Build Quality
The WS-12 is designed to fit under desks for use in small studios. By adding handles and
using high quality materials for the cabinet, Kali Audio has made the WS-12 roadworthy
and ready for live duty. The subwoofer will fit easily into most small cars.
Low Noise Port Tube
Similar to the LP-Series Studio Monitors, the port tube on the WS-12 was designed to
deliver all the benefits of a front-firing port tube, without any drawbacks associated with
noise.
On most port tubes, air leaves at different speeds from different points of the opening,
creating noisy turbulence. This turbulence can be heard as “chuffing,” or an audible air
sound coming from the subwoofer. This sound will add to the noise floor and obscure the
details of the low end.
The port tube on the WS-12 was designed to ensure that all of the air leaves the port tube
at the same velocity. This helps add to the low end response of the subwoofer, while keeping the bass clean, tight, and devoid of extra noise.
Robust Configuration Options
Because the WS-12 is designed to serve in such a wide variety of applications, it is
equipped with features to allow you to get the most out of it, whatever your use case. The
back panel features switches to control the crossover frequency, the level of the subwoofer, the polarity, and various inputs.
Users can bypass the sub using a third-party on/off footswitch with a 1/4” connector. Such
footswitches are readily available from any musical equipment retailer.
