The iS115 passive subwoofer has been designed to provide a deep bass extension to column loudspeakers such as StepArray, for diffusion of music or AV soundtracks. iS115 is very compact, and can be positioned horizontally or vertically, thus ensuring optimum integration. The 15" high-end neodyme loudspeaker is loaded in bass reflex. It achieves a remarkably low cutoff in a small volume, while yielding sharp and dynamic sound.
