Not just an active 18-inch subwoofer, the Thunder-KMT18 I is also a proper instrument for the management and processing of the audio signal. Internally integrated is a 2-channel, 1000 W @ 8Ω Class D amplifier with one channel dedicated to the 18" woofer and the other connected to a speakOn output on the rear panel, 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.

 

The KMT18 features an integrated touch screen, providing intuitive control over the main DSP functions: input/output levels, signal routing, offset delays for subwoofer and speakon output (up to 12 ms) 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 analogue line level inputs and a two-channel AES/ EBU digital input. An integrated class D amplifier delivers 2 x 1000 W at 8Ω, with a max THD of 1% (EIAJ test @ 1kHz). The KMT18 I features multiple analogue and digital outputs, including a Speakon output to connect a wide array of passive speakers including mid-high models (KK52, KK102) or additional passive subwoofers (KMT18P). 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 theatres, concert halls, and Audio/Video installations.

“By far the best service I’ve ever experienced. I was importing a product to Canada and the whole experience was quick, easy and seamless. These guys really care about running a good business. Not to mention the price was cheaper than the stores here even after importing. Definitely will do more business in the future.”
