The K-array KMT21 I is a powered 21-inch subwoofer, with a programmable on-board DSP and multiple analog and digital inputs and outputs for creating a wide array of speaker configurations. The amplifier mounted on board is class D, delivering 2 x 2000 W at 4-OHM. The KMT21 I feature an integrated touch screen, providing intuitive control over the main DSP functions: input/ output levels, signal routing, offset delays for subwoofer and speakon output and overall system delay (up to 330 ms). All DSP functions, including EQ, can also be remote controlled via software over USB or RS485 (3-pin XLR). The KMT series provides two balanced analog line level inputs and a two channel AES/EBU digital input. An integrated class D amplifier delivers 2 x 2000 W at 4-OHM, with a max THD of 1% (EIAJ test at 1kHz). The KMT21 I feature multiple analog and digital outputs, including a Speakon output to connect a wide array of passive speakers including mid-high models (KP52, KP102) or additional passive subwoofers (KMT21P). To optimize performance, the on-board DSP includes up to 40 programmable presets. The unique four-corner port configuration provides symmetrical back loading to the speakers, for extended bass response with very low distortion. The port configuration also provides incredible structural strength to the cabinet, despite its light weight. Pocket handles and an M20 thread mount position for attaching mid-high speakers makes the subwoofer convenient to use and ideal for medium throw applications in theaters, concert halls, and Audio/Video installations. All KMT components are designed by K-array and custom made under K-array’s quality control system.
