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 V2 is rugged and portable, making it a perfect solution for us 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 versions. 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.
