The cardioid subwoofer.
Despite its small frame size, the P WK reproduces the lowest frequencies in an impressively dry, clean, powerful and directed way. This is achieved by two separated vented chambers, each with a 15′′ speaker of the highest quality and power capacity. What makes the P WK very special
is the enormous power handling capacity of 2,600Wrms achieved by 2x15” long-excursion woofers with 100mm voice coils and rib-reinforced membrane, as well as their arrangement in push-pull operation.
Three different operating modes enable an effective cardioid radiation, conventional parallel connection or reproduction of two stereo basses in only a single cabinet. The ideal control- led amplifier is a KS AUDIO TA 2D. It provides the required performance, response correction and safe protection for the speaker. With the appropriate controller setting, a perfect cardioid radiation is achieved over a wide frequency range.
A stereo crossover is also available and allows operation of the P WK as a mono subwoofer. In this mode the low-fre- quency signals of the stereo channels are added on both outputs and then delayed and phase-
corrected in such a way, that up to four (!) P WK can be operated as cardioid subwoofers driven by a TA 4D amplifier.
The format of the P WK makes it particularly suitable for applications where little room is available on the stage, and especially where it is supposed to be flown in combination with a P LINE or VC LINE array.
Alternatively a distance rod with an M20 thread can be used.
Four big transport wheels are mounted on the rear side. The solid protective grille covers the entire front and optionally, is covered with acoustic foam.. The acoustic opening at the back is also custom covered by a sturdy grill that is neatly recessed into the housing.
The fly-ware is fully integrated into the housing and is suitable for VC LINE and P LINE array.
A transport protection cover is available as accessory.
