Kali Audio WS-12 V2 12-Inch 1000W Studio/Live Subwoofer

About: Kali Audio WS-12 V2 12-Inch 1000W Studio/Live Subwoofer

Kali Audio's WS-12 V2 is a 1000 W, 12-inch subwoofer for studio and live use. With a frequency response down to 23 Hz, it is an authoritative studio subwoofer. The 1000 W power amp allows the WS-12 to be used for bass management in 5.1 systems, and one WS-12 will be sufficient when using up to 5 of Kali’s IN-8s.

The WS-12 is the only subwoofer that can pull double duty as a studio and live subwoofer. An 18mm wooden enclosure means that the WS-12 V2is rugged and portable, making it a perfect solution for use in small PA systems. The WS-12 V2 is specifically designed to fit into small passenger cars, making it easy to carry to and from gigs.

V2 features several improvements over the original version. Signal-to-noise on the crossover is improved by more than 6 dB. The V2 also features an M10 pole cup, allowing users to attach a pole for mounting full-range PA speakers.

1000 W Amplifier/ 123 dB Max SPL

The WS-12 V2 uses a Class D power amp capable of 1000 W peak power and 500 W continuous power. This allows the WS-12 V2 to play up to 123 dB Max SPL; enough SPL to provide LFE for at least a 5.1 system of IN-8s. In many listening environments, 1-2 WS-12s can easily handle both LFE and bass management for a full Atmos system.

30 Hz at +/- 3dB

The WS-12 is fully compliant with Dolby’s specifications for subwoofers to be used for Atmos monitoring for both music and picture.

Low Noise Port Tube

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 monitor. This sound will add to the noise floor and obscure the details of the low end.

The port tube on the WS-12 V2 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 speaker, while keeping the bass clean, tight, and devoid of extra noise.

• Extended bass response
• Port tube does not add to noise floor
• Air leaving the port tube is neither heard nor felt

Selectable crossover

The WS-12 V2 has a user-selectable crossover with 5 Hz steps from 50 to 110 Hz. This allows users to integrate the WS-12 with any pair of stereo speakers, including studio monitors, hifi speakers, and PA speakers.

Most studio monitors, including all models offered by Kali Audio, will work best with the 80 Hz setting.

• Simple routing for stereo setups
• Ease of integration with a variety of full-range speakers

Polarity Inversion

The polarity reverse function on the WS-12 allows you to flip polarity by 180 degrees to better integrate with the full range speakers and the room

Footswitch 

You can use a foot switch, sold separately, to turn the subwoofer off and disable the crossover, allowing you to hear full range signal through your studio monitors without the sub when you want to check your mixes.

Road-Ready

The WS-12 V2 is ready for live use. With an 18-mm plywood enclosure, a steel grille, and a rugged, textured coating, it can stand up to stage duty and the abuses of being transported night in and night out. Steel handles make the WS-12 easy to carry, and its dimensions are specifically tailored to fit into the trunk of a Toyota Corolla, meaning that it can be easily transported in most passenger cars.
