Kali Audio WS-6.2

Compact studio subwoofer

The Kali WS-6.2 is an active studio subwoofer fitted with two 6.5-inch woofers mounted face to face, powered by a 400 W continuous Class D amplifier. Designed as a companion to Kali's LP and IN Series monitors, it also works with most studio monitors and reaches down to 27 Hz (-10 dB). About the size of an 8-inch monitor, it is a compact subwoofer well suited to the home studio.

Two opposed woofers, no vibration

The two 6.5-inch woofers fire sideways, horizontally opposed. Their movements cancel each other out, so the cabinet does not vibrate or creep across the floor, even at high levels. Together they offer the same radiating area as a 10-inch woofer, with 15 mm of peak-to-peak excursion. The front port is designed to avoid chuffing noise and keep the low end clean, and a built-in limiter protects the subwoofer from excessive levels.

Integration with your studio monitors

The WS-6.2 sits between your audio interface and your monitors. In 80 Hz mode, it reproduces everything below 80 Hz and sends the rest of the signal, high-passed, to your monitors through its two XLR outputs. This crossover is designed for Kali monitors but also suits most popular models: Kali names the Adam A and T Series, KRK Rokit, JBL 3 and 7 Series, PreSonus Eris and Yamaha HS. LFE mode applies a 120 Hz low-pass filter so the sub can serve as the .1 channel in a 2.1 system or a small 5.1 setup, and External mode passes the signal unfiltered when you use an external crossover. A polarity switch helps you get the best blend between the sub and the monitors depending on where they sit in the room.

A compact subwoofer for the home studio

At 40 x 36.8 x 27.9 cm and 14 kg, the WS-6.2 takes up less than half the volume of subwoofers with comparable performance and fits easily under a desk. It is designed to reach studio reference level at listening distances of up to 4 meters, which covers most small control rooms. The footswitch input (pedal sold separately) lets you switch the sub off with your foot: the monitors then receive the full-range signal, handy for checking how a mix holds up without a subwoofer.
