The WS-12 V2 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 V2 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 V2 is powered by a 1000W power amplifier mated to a high-excursion 12-Inch driver.

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 youre using it with a pair of LP-6s, as bass management in a 5.1 system, or on stage with a PA, its easy to configure the WS-12 V2 to get exactly what you need.

Features:

Selectable Crossovers
The WS-12 V2 has selectable crossovers every 5 Hz between 50 Hz and 110 Hz.

Gain Adjustment
6 dB steps allow easy adjustment between free space, against walls, or in corners.

Polarity

Footswitch

The WS-12 V2 was designed as a companion subwoofer for Kalis LP- and IN-and SM-Series studio monitors.

When used with a pair of Kali monitors, the subwoofer can handle both bass management and LFE for any system of up to 5 of Kalis full range speakers. Two WS-12 V2s will be sufficient in most immersive applications, and the placement of the subs can help solve low end problems in your room.
