The Mastiff-KM112 is self-powered compact monitor. It features a coaxial 12” woofer and can reach a maximum SPL of 133 dB (peak). It's self-powered with a power output to drive the KM112P passive version, which in turn can drive a stereo mix as well as a Thunder-KMT18P for a drum fill, making it one of the most versatile monitors on the market.

Color Customizable

We have the ability to customize your project by color matching your system to any RAL code to help you to better integrate the speakers into a wide variety of venues.



Full-Range Frequency Response

With a very extended frequency range the loudspeaker covers the entire audible spectrum without the need for a subwoofer ideal for when there are space constraints.


Dante Compatible

With the dedicated K-dante accessory, this solution can be integrated into a Dante network making it interoperable with other devices.


Selectable Coverage

The directivity of many K-array solutions can be modified in order to optimize the coverage by an adjustable horn with variable orientation.


Spot/Flood Dragon
Onboard Touch Screen

An integrated touch screen provides intuitive control over the main DSP functions: input/output levels, signal routing, offset delays for the subwoofer and Speakon output and overall system delay (up to 330 ms).


Self-Powered Capabilities

Our self-powered solutions prevent distortion from cumbersome and fragile passive crossovers and power loss due to long running cables, and offer plenty of advantages ranging from the compactness of the solution to the ease of integration with new and existing sound systems.
