12 Inch 3-Way Full Range Loudspeaker System

Ki512 is a full-range speaker designed specifically for KTV applications. The 3-way speaker combines a 12” woofer, a 5” squawker and a 1” aluminum dome tweeter and is able to handle continuous power of 400 Watts.

The high-power 12” woofer features a long fiber pulp cone and pure nitrile butadiene rubber surround and provides necessary stiffness and capacity to withstand the tremendous accelerating force from the motor. The 5” paper cone squawker and the 1” aluminum dome tweeter optimizes middle and high range reproduction and guarantees non-compromised sound quality for the whole speaker system.

Ki512 takes on a bold and unique appearance. Its asymmetric cool brown enclosure echoes the deliberately-defined three-way system. The clear-cut outlines indicate the quality and performance the speaker possesses. The front panel comprises a paillette fabric and a snow-flake patterned grille and highlights a rose gold strip. The trendy enclosure creates an air of elegance and professionality.
