Kali Audio WS-12 12-in Active Subwoofer



12-Month Special Financing**


Kali Audio’s WS-12 is a 1000 W, 12-inch subwoofer for studio and live use. With a frequency response down to 25 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 is rugged and portable, making it a perfect solution for use in small PA systems. The WS-12 is specifically designed to fit into small passenger cars, making it easy to carry to and from gigs.

WS-12 Features:

1000 W Amplifier

The 3-D Imaging Waveguide allows you to hear a 3-D soundstage from a stereo pair of speakers. By matching the shape of the waveguide to the interactions of the HF and LF drivers, this waveguide produces a stereo image that is wider, taller, and deeper than the space where the speakers are placed.

The LP-6 accomplishes this by ensuring that the speaker’s reflected sound matches its direct sound. Every time you hear a loudspeaker, you’re hearing both the direct sound from the speaker, and reflections from the speaker’s signal bouncing off of objects in the room.

When those reflections are congruent with the direct sound from the speaker, listeners perceive a better sound overall, and are able to make out very subtle details like where microphones are placed in a room. When done very well, the stereo image will be three-dimensional.

This gives users a very high degree of confidence in their mix. It allows them to mix faster, and produce better mixes overall.
