Thunder-KMT12 I

A smart 12" subwoofer with the power of a 2-channel, 1000 W @ 8Ω Class D amplifier, the Thunder-KMT12 I allows many different configurations in combination with passive K-array loudspeakers like mid-high speakers, entire column line arrays or other passive sub to reinforce the mid-low frequencies.

Although it is the smallest of the line, the Thunder-KMT12 I has the same computing power as the other Thunder subwoofers for reproducing sound, rending it ideal for applications that require a small visual footprint with a large sound.
