The K1-SB is a great subwoofer speaker supplement for the K1 and K2 line array speaker. It increases the resources at the low end frequencies of the systems, by reinforcing their contour or by improving their capacity to carry the bass at long distances.
The K1-SB passive pa subwoofer is equipped two 15 " neodymium low frequency speaker driver in a bass-reflex tuned cabinet. It delivers impact and high sensitivity, while maintaining distortion and thermal compression at extremely low rates.
The bass-reflex vents have a progressive profile that produces a laminar flow and reduces turbulence noises, even at the highest sound levels. All of these properties contribute to the sound qualities of the KI-SB: precise definition of the bass and excellent musicality.
The 15 subwoofer speaker box is made from first-class Russian birch plywood, ensure that its remarkable mechanical and acoustic properties.
The 4-point attachment system integrated into the subwoofer cabinet is compatible with the K1 and K2 systems. K1-SB speakers can thus be suspended as a stand-alone assembly, or within a K1 / K1-B or K2 / K1-SB mixed line.
