K Series Network Active speaker integrates function of network transmission, remote control & monitoring, with built-in class D digital amplifier, is a full range speaker. It features high effective, outstanding sound, complete protection and perfect compatibility of electromagnetism. Users can monitor and adjust the speaker remotely through a CAT5 line by computer. The speaker can receive audio signal from network via the built-in CobraNet board.

Features of K15M Network active speaker: 
1) K12: two-way, 12” woofer + 44T tweeter 
2) K15: three –way, 15” woofer + 75T mediant + 44T tweeter
3) K15M: two –way, 15” woofer + 44T tweeter
4) K30: three –way, 2*15” woofer + 75T mediant + 44T tweeter
5) K18: 18” subwoofer
6) It adopts CobraNet technology, with backup analogue input & CobraNet input.
7) Users can control and monitor the working temperature, loading, voltage and current of the speaker remotely by PC, and achieve gains control & long distance power on and off .
8) By using one CAT5 line and RJ45 connectors, audio transmitting, controlling and monitoring can be achieved, very easy for installing and operating.
9) The mid-high and woofer is respectively driven by class D amps. 
10) With complete protection(short-circuit protection, over current protection, over and under voltage protection, DC protection, power compression, temperature compression, long time power output limit, clipping limit)
11) K series network active speakers are based on switching technology and auto control technology that has been used for over 40 years. The switching technology provides high reliability, small size, low weight and high efficiency. A PMC converter works as a high frequency sampler, converting the variable amplitude (audio) signal into an impulse sequence with average value equal to the audio input. The speaker uses very high frequency conversion rate to obtain high performances.
12) Open choice of AC100-220V global power supply.
13) Independent MCU control, independently running without computer.
14) User can control every channel independently.
15) All setup parameters can be stored in the memorizer. 
16) Firmware is updatable via RS232 port.
17) Redundant network connection
