The K-array KMT21 I is a powered 21” subwoofer, with a programmable on-board DSP, multiple analog and digital inputs & outputs for creating a wide array of speaker configurations. 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.
The amplifier mounted on board is class D, delivering 2 x 2000 W at 4Ω. The KMT21 I features an integrated touch screen, providing intuitive control over the main DSP functions: input/output levels, signal routing, offset delays for subwoofer, 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 4Ω, with a max THD of 1% (EIAJ test @ 1kHz).
The KMT21 I features 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.
