Coaxial systems have the ability to cumulate low and high frequency outputs on all positions of the off-axis to transcend into a point source. This helps combat uneven frequency response in the crossover region especially close to the loudspeaker, establishing coaxial devices as the optimal solution for near field applications where pressure is needed upfront. However, a significant detractor of a traditional coaxial device is the reduction of high frequency dispersion when frequency increases. K-array’s solution is the KX12.

Uniquely designed, like all of the other products in K-array’s portfolio, the KX12 is a radical interpretation of a traditional coaxial 12” speaker. While most coaxial speakers are constricted by their wedge shape to be linked to other units at the same fixed angle, the KX12 has the flexibility to be adjusted to any desired incline as a single array element. 
It maintains a balanced dispersion pattern at all frequencies on the axis through a horn with an adjustable orientation.

Consistent frequency and SPL at any point in the coverage area can be expected from the fixed dispersion, 100° by 30° horn. The ability to rotate the horn and select between a more narrow, vertical coverage or a wide, horizontal coverage based on the needs of the event, install, sound design, etc is one of the biggest advantages the KX12 holds. 


The exceptional coverage provides the freedom to spread out the setup of the system and even decrease the amount of speakers needed making the KX12 one of the most useful tools to an installer.

Additionally, dedicated accessories assist in the set up of joining, flying and stacking the speaker, making it a perfect line array component. The KX12 can be flown with up to 8 units with a safety factor of 7:1 to form a line array in which each speaker can be individually adjusted with a different horn position to put sound farther and wider then a typical line array. 

Its compact, steel chassis offers maximum rigidity in a minimum size. The speaker delivers a continuous SPL of 127 dB and has a frequency range of 150 Hz to 18 kHz. It is compatible with all K-array KMT subwoofers because of the dedicated presets stored on board every K-array amplifier. 

KRX Systems 
By combining the KX12 with active K-array subwoofers, three new portable systems -which differ in size of active subwoofer and number of KX12 units used - have been added to K-array’s portfolio.

With powered subwoofers that maintain the same digital editing features of all K-array active subwoofers, the KRX systems feature an integrated touch screen, providing intuitive control over the main DSP functions, such as input/output levels, signal routing, offset delays for subwoofer and mid-high speaker output (up to 12m each) and overall system delays (up to 330m). All DSP functions, including EQ, can also be controlled remotely via software through USB or RS485 (3 pin XLR). 

The systems include dedicated accessories that provide a multitude of setups based on the application. The K-JOINT2B is a versatile piece of hardware with fixed angles used to adjoin two KX loudspeakers with the possibility to adjust the angle several degrees.

A 35mm extension pole is also included to position the loudspeakers on the subwoofer for a column arrangement. To fly a KX12 line array, the K-FLY2B is a dependable, durable fly bar that can be purchased separately. 

The KRX202 is the smallest of these three new systems and is composed of two KX12 speakers coupled with a pair of KMT18 18” subwoofers and includes an extendable pole and proper joining and stacking hardware. Possible applications are DJ sets, clubs and anywhere a lot of pressure is needed close to the speakers.

The KRX402 is the middle range system that delivers more pressure and a more extended bass response than the smaller KRX202. It is comprised of four KX12 speakers paired with two 21” KMT21 subwoofers.

The largest of the three systems is the KRX802. With six KX12 speakers combined with two KMT218 dual 18" subwoofers, the system converts into a line array that delivers maximum SPL, very low frequency and best bass response. No longer a point source, the KRX802 covers larger distances with higher pressure in larger venues.
