With a depth of only 11 inches, the new KPT-418 cinema subwoofer is even more compact than the KPT-884. Serving as a replacement for the KPT-484, this high-output, bass-reflex subwoofer system delivers true bottom-end performance along with high power handling capability and high efficiency. It can be used as the main subwoofer system in a small auditorium or as the subwoofer for surrounds in small- to medium-sized auditoriums.
