KEN KREISEL, the inventor of the active subwoofer, created the M&K that represents the standard for studio monitoring. As the new generation flagship subwoofer of the KK brand, the DXD1000 must take on the heavy responsibility of the soul of the cinema. Rated power of up to 1000w, heavy-duty push-pull unit, based on KK's consistent precision and speed, brings a larger output. As KK's flagship subwoofer, it truly lives up to its name. 4 pieces can be superimposed to create a Quattro subwoofer column, forming a structure of 4 pieces of Push-Pull, so that the subwoofer under the Push-Pull structure can reduce distortion, and at the same time bring lightning-fast, thunderous low frequency.
