Kali Audio's WS-12 V2 is a 12" subwoofer with a frequency response down to 23Hz. This authoritative studio subwoofer has 1,000 watts of power that 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 five of Kali's IN-8s. The WS-12 is the only subwoofer that can pull double duty as a studio and live subwoofer. An 18 mm wooden enclosure means that the WS-12 V2 is 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. This version features improved signal-to-noise on the crossover by more than 6dB and a M10 pole cup that allows users to attach a pole for mounting full-range PA speakers.
