K-S28 is a reference subwoofer, designed to extend the frequency response of large format systems. The K-S28 features two high excursion, 18’’ direct radiating transducers mounted in a bass-reflex tuned enclosure. The optimized L-Vents laminar vented port reduce turbulence and port noise at high levels while also increasing LF efficiency.
