The S-81W-MK is a compact sized, matte black active subwoofer. Integrating a 300W D-class amplifier, it reproduces the source signal with strength and precision, avoiding distortion and uncontrolled sound restitution for even the lowest of frequencies. Sharing the DNA of our EX Series speakers, this sub's 30cm driver features a linear magnetic circuit that improves the linearity of the cone’s displacement even at the highest power. Aside from featuring a 0°/180° phase switch, the panel setting allows you to select the crossover frequency of the internal filter (or to bypass it). It also has a dedicated “Cinema mode” switch that will enhance any movie soundtrack to give you a unique cinematic experience. A line output connector makes it easy to link with another subwoofer, which is recommended for particularly large rooms.
