Thunder-KMT218

Just like the other subwoofers in the Thunder line, the Thunder-KMT218 is much more than a standard dual 18” powered subwoofer.

This smart sub has an onboard Class D amplifier that delivers 2 x 2000 W at 4Ω with one of the two amplifying channels dedicated to the power supply of the sub while the other is dedicated to a Speakon output to create many different speaker configurations, including single mid-high modules, multiple line arrays, or the passive version of an additional bass module.
