The KSK92 subwoofer stacking kit is designed to effortlessly merge up to three KC92 subwoofers into a single, powerful unit. With easy installation via threaded inserts on the rear plate of the KC92, stacking subwoofers vertically is a breeze, and can help deliver even higher levels of output and performance, without sacrificing valuable floor space. Stacking KC92 subwoofers can increase the maximum output by up to 9.5dB – the difference in listening to a rock concert and hearing a jet plane take off from the runway. Alternatively, each subwoofer can be played at a lower level individually, providing better dynamics and headroom for a more accurate performance. Crafted from durable aluminum, the frames provide a sturdy foundation, while a soft material layer sits between each subwoofer, ensuring they remain scratch-free. By positioning the frames discreetly at the rear after stacking, the result is an excellent audio experience and a clean, seamless aesthetic.
