Active 2 way mono system

K4m is a system designed for musicians, singers, DJs and speakers, who requires a high sound quality as well as
equipment easy to mount and transport.
The system offers incomparable performances both in closed and open spaces. It is recommended for users requiring
an intense sound uniformity and strong power in middle sized and large environments.
The system, led by a powerful DSP, is placed in a “SUB” speaker, which is protected by scratch-resistant paint,
containing two classes “D”, 1000 watts amplifiers.
The first amplifier drives the 15” woofer, which is placed in the “SUB” speaker; the second amplifier, whose output
power is electronically limited to 600 watts, manages the “TOP” mid-range and high frequencies speaker.
