Congratulations on your Kali Audio WS-12 V2 Studio/Live 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 Kali's subwoofer 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 our subwoofers.
Features
12-Inch Woofer
The “12” in the WS-12 V2’s name alludes to the high-excursion 12-inch woofer at the heart of the subwoofer. This woofer uses a large motor with a 2.5-Inch voice coil for high power and minimal distortion.
Output
The WS-12 V2 is designed to provide reference level output at a distance of 5 meters. This makes it an ideal subwoofer for near-to-mid field monitoring where high power is required. One subwoofer has enough output to provide both LFE and bass management with up to 5 of Kali's most powerful speakers, and two WS-12s will be sufficient in most immersive systems using Kali's full-range speakers.
The WS-12 V2 will be an excellent companion to both Kali Audio speakers, and other speakers and studio monitors that are designed for near-to-mid field monitoring.
Kali Audio uses Dolby's music studio reference level spec, which is 85 dB continuous output at the listening position, with 20 dB dynamic headroom, or 105 dB peaks at the listening position. For help configuring a system in Dolby's room design tool (the DARDT,) using the WS-12 V2, contact Kali's customer support.
Low Noise Port Tube
Similar to the LP-Series Studio Monitors, the port tube on the WS-12 V2 was designed to deliver all the benefits of a front-firing port tube, without any drawbacks associated with noise. This allows the WS-12 V2 to have even lower bass extension, while delivering clean, tight, punchy bass.
About Your Subwoofer
Features
Footswitch Bypass
Turn off the subwoofer and listen to your mix through your full-range speakers so you can hear how it will translate to systems that don't have a sub. Footswitch sold separately; most music retailers sell a variety of 1/4-inch footswitches that will work. Contact Kali Customer Support if you need assistance in selecting a suitable footswitch.
Limiter Circuit
The WS-12 V2 is equipped with a limiter circuit that will protect the speaker from unsafe operating levels. In other words, you don't need to worry about blowing up the subwoofer by playing it too loud.
Unsafe playback levels 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. In some cases, the subwoofer will shut itself down to protect itself from harm. See page 18 for what to do if this happens to you.
Road-Ready Enclosure
The WS-12's immense power makes it useful as a light-duty subwoofer for live music. It features a road-ready finish that won't easily scratch when being transported and setup, and steel handles for transportation.
On the top of the sub, there is an M20 threaded pole cup to accept speaker poles for mounting PA speakers above the subwoofer.

Inputs and Controls
Dip Switch Quick Reference Guide
The quick reference guide on the back of the speaker can help you set the dip switches to the appropriate positions for your application without needing to consult this manual.
Use the 80 Hz crossover (DIP switches 2 and 3 UP) for Kali loudspeakers. A full explanation of the DIP switches can be found on pages 13-16.
XLR Outputs
Use the XLR Outputs to pass signal through the subwoofer and to a stereo pair of speakers. The signal from the subwoofer will be high-passed according to the crossover set with dip switches 1-4. If using more than 2 full-range speakers, it is recommended to use an external processor and crossover.
Inputs and Controls
3
XLR/TRS Combi Jack Inputs (+4 dBu Sensitivity)
The XLR/TRS input is for use with professional audio devices like mixers, interfaces, and controllers. Depending on your device, it will either use XLR or 14 " TRS outputs, either of which can be used with this input.
4
RCA Inputs (-10 dBV Sensitivity)
The RCA input is for use with consumer devices like record players, laptops, smart phones, and media players. Commonly, the playback device will either have an RCA or a 3.5mm (Aux) output. Cables from either of these outputs to RCA are easy to find.
5
Volume Control
The volume control allows users to adjust the output of the speaker from - (Muted) to +6 dB. There is a center detent at the +0 dB setting.
If you have your main speakers running off the outputs of the WS-12, start with the volume all the way down, and slowly bring it up.
6
Dip Switches
The dip switches control crossover, location-based gain, polarity, standby mode, and input gain. A full explanation of the operation of the dip switches can be found on pages 13-16.
7
Footswitch Input
The footswitch input allows for a footswitch to be connected to the subwoofer to toggle between normal operation and bypassed operation. When the subwoofer is bypassed, the subwoofer will no longer play, and the high-pass filter on the outputs will be disabled. In other words, full-range speakers connected to the outputs will behave as though they are not connected to a subwoofer at all.
When the subwoofer is bypassed, the LED on the front will flash blue.
No footswitch is sold with the WS-12. Any common toggle switch with a 1/4-Inch connector will work. These are available for sale at any music retailer.
8
Power Input
Connect the provided power cord to this input. Before powering the unit on, be sure that the 110V-230V switch (10) is set to the appropriate setting for your location. Most areas in North America use 110V power, and most areas in Europe use 220V power. If you are unsure of the voltage in your location, search “Local Voltage (Name of your country.)”
Inputs and Controls
9
On/Off Switch
Power the speaker on and off. Be sure to power the speaker off when connecting or disconnecting the power cable, during lightning storms, or during extended periods of disuse. Before powering the unit on, be sure that the 110V-230V switch (10) is set to the appropriate setting for your location. Most areas in North America use 110V power, and most areas in Europe use 220V power. If you are unsure of the voltage in your location, search “Local Voltage (Name of your country.)”
10
110V-230V Power Switch
The WS-12 requires you to select the appropriate input voltage for your location. Before powering the unit on, be sure that the 110V-230V switch (10) is set to the appropriate setting for your location. Most areas in North America use 110V power, and most areas in Europe use 220V power. If you are unsure of the voltage in your location, search “Local Voltage (Name of your country.)”

Power LED
The LED on the front of the WS-12 indicates power, bypass mode, and standby.
Solid Blue: The WS-12 is on and functioning normally.
Flashing Blue: The WS-12 is on, but bypassed. The subwoofer itself will not make sound, and the high-pass filter on the outputs is bypassed. Full range speakers connected to the subwoofer will behave as if they are not connected to the subwoofer.
Solid Orange: The WS-12 is on, but in standby mode. To wake the subwoofer up, play signal through it.
Dip Switches
Like the LP-Series Studio Monitors, the WS-12 features easy-to-use dip switches on the back that help you configure it to your specific application. Note that each set of switches is completely independent of one another, so any adjustments you make to one set of switches will not affect any other set of switches.
Switches 1-4: Crossover
These switches control a low-pass filter that passes signal to the subwoofer, and a high-pass filter that passes signal out through the XLR outputs. If you're using more than 2 full-range speakers, it is recommended to set the crossover to "External" and use an external processor and crossover.
Positions 1-13: Variable Crossovers
The crossovers on the WS-12 V2 send low-passed signal to the subwoofer itself, and a complementary high-passed signal via the XLR outputs. Crossovers can be set every 5 Hz between 50 Hz and 110 Hz.
For all Kali Audio speakers, and most common studio monitors, Kali recommends using the 80 Hz crossover. (DIP Switches 2 and 3 UP)
For other speakers, multiply the speaker's lower frequency response spec by 2, and then round up to the nearest crossover point. For example, with an LP-6, the lower frequency response is 39Hz . Multiplied by 2, that feature is 78Hz . Round this up to 80Hz and use that crossover.

Position 15: External Crossover
The subwoofer is receiving low-passed signal from an external source, and full range sound is being crossed over and processed by an external processor. Use this setting if you want to use your own crossover, or if you're using a system larger than stereo. Note that in this position, the subwoofer will play up to about 1 kHz unless the signal you send to it is low-passed. This position will not send signal through the subwoofer's XLR outputs.

This is the recommended setting if the subwoofer is being used with a larger system, at a greater distance, or in a live sound setting. This setting will deliver the subwoofer's maximum output.
Switch 5: UP
Switch 6: UP
Switch 7: Polarity
Depending on the shape and size of your room, the position of the subwoofer relative to the monitors, and your listening position relative to all of those factors, the subwoofer may sum better with the monitors with the polarity reversed. To test which setting is more appropriate, simply try both settings, and use the one that sounds better. It is also possible to use free software such as Room EQ Wizard (REW) to test the polarity of your subwoofer. Instructions for doing so are readily available with a quick internet search.

Position 2: 180°
Switch 7: UP
Dip Switches
Switch 8: Max Input
Depending on your source, you may wish to raise or lower the input sensitivity on the balanced inputs. +14 dBu should be used for lower power sources. This includes most desktop USB interfaces, and many live music mixers. If you find that you're clipping with the +14 dBu setting, use the +20 dBu setting instead.
+20 dBu should be used for higher power sources, like professional recording consoles. If you find that you're not getting enough output using the +20 dBu setting, use the +14 dBu setting instead.
Position 1: +14 dBu
Switch 8: DOWN
Position 2: +20 dBu
Switch 8: UP
Switch 9: Standby Mode
The WS-12 is equipped with a standby feature which will put the subwoofer into a low-power mode after 20 minutes of disuse. In low-power mode, the power LED will turn orange, and the subwoofer will not pass audio. The subwoofer will come back online once it receives signal. If this operation is not desired, turn switch 8 up to disable standby mode.
Position 1: Standby On
Switch 9: DOWN
Position 2: Standby Off
Switch 9: UP
First Time Setup
Once the subwoofer is in position, follow these steps to get it turned on and playing for the first time.
- Make sure that the power switch on the sub is set to the OFF position.
- Turn the volume control on the back of the sub all the way down.
- Plug the subwoofer into power.
- Plug in your audio cables from your source, and, if you're using the WS-12's built-in cross over, to your main speakers.
-If you're using the WS-12's crossover, also power off your main speakers, and set their output to a nominal level. - Turn on your audio source.
- Power on the subwoofer and speakers.
- Slowly turn the volume on the subwoofer up to the center detent. If you hear distortion, turn the subwoofer back down and check that all of your connections are tight.
- Use the volume knob on the subwoofer to adjust its level relative to the main speakers.

1. I opened the subwoofer, and it is damaged.
If you received a speaker that is obviously damaged, please contact your dealer immediately.
2. The subwoofer is making no sound.
• Is the subwoofer plugged in?
- Is the subwoofer turned on? There should be a blue LED on the front of the subwoofer if it's on. If this light is off, the subwoofer is turned off.
• Is the volume turned up?
- Have you made sure that the subwoofer is not being bypassed using a footswitch?
- Are all cables plugged in to both your playback device and the subwoofer?
- Are you passing audio via your playback device?
3. The subwoofer sounds distorted.
- Is the subwoofer playing too loud? Turn down the volume on the back of the subwoofer. If the distortion goes away, you may be playing the subwoofer too loud. Besides the problem of distortion, this can be damaging to your hearing if you are close to the subwoofer.
- Is your source too loud? Turn the volume down at your source device. If the distortion goes away, you may be overdriving the input. If this is the case, turn the volume of the subwoofer up with the volume control on the back.
4. I hear crackling, hums, or buzzing.
- Are you using RCA?
a. If "yes," be advised that RCA is an unbalanced connection, and is prone to picking up noise as signal travels through the cable. This is especially true if you are using very long RCA cables.
- Is the subwoofer close to electronics like a television, wireless router, phone, motor, or radio? If so, these can interact with the speaker's electronics in ways that cause unwanted noise. Try moving the subwoofer at least .5 Meters (20 inches) from any such devices.
- Are there loose objects in the room that may be buzzing with the bass? Low frequencies can cause objects in a room to vibrate loudly. Make sure that small, hard objects like screws and other hardware are secure.
5. The subwoofer stops playing.
- If the subwoofer stops playing but the blue light stays on, you may be engaging it's thermal protect mode, which will shut the subwoofer down so that it does not damage itself. Power the subwoofer down, wait 2-3 minutes, and power it back on.
- If the subwoofer plays after being turned off and on again, reduce the output level of the sub, and make sure it is in a cool, well-ventilated area so that it does not overheat.
If none of the above solves your problem, contact your dealer to initiate a return.
