The WS-6.2 is a studio subwoofer with 2 x 6.5-inch high excursion woofers. Designed to be both powerful and small, the WS-6.2 takes up less than half as much space as comparably performing subwoofers. Despite its diminutive form factor, it is capable of 120 dB max SPL and 27 Hz lower frequency response. The woofer are horizontally opposed, meaning that there is no net vibration from the subwoofer. A built-in 80 Hz high-passed output makes it ideal for pairing with most popular studio monitors, including Kali's LP-and IN-Series monitors. A footswitch jack allows users to bypass both the sub and the crossover so they can hear their mix on their full range speakers. Footswitches are sold separately, but a number of inexpensive options are available at every music retailer. In addition to the 80 Hz crossover, the subwoofer can be set for LFE mode or be used with an external crossover. Polarity may also be reversed if necessary. Like all of Kali's speakers, the US-6.2 uses a unique port tube that virtually eliminates chuffing and port compression, allowing for clear, powerful bass with minimal distortion.
