M-Series
The M Series - Our "Audio Chameleon"Our M series adapts to the world of different public address tasks as perfectly as a chameleon fits in with its environment.
High-quality birch multiplex serves as the base for the sturdy housing, for standing up to years of the everyday rigours of being "on the road". The horn tweeters can be turned 90° when required. All horn designs have been developed using BEM (boundary elements method) and optimised for the driver being used. Extraordinary fidelity, low distortion factor and constant directivity up to over 15 kHz – facts that you can simply hear.
All M series loudspeakers allow passive full-range operation on standard amplifiers without further system controllers. And that is with a real "big system" sound. Weight is the only thing that we have saved on: at 26 kg even the big M15 is "solo-carrier friendly".
Thinking forward:
Of course, all of the "Ms" have a recessed high stand flange. The M8 possesses lots of inset screw threads for the screwing-on of mounted accessories. It also has four connection sockets.
The M12 and M15 are equipped with air-cargo flight rails as standard, using which optional swivel brackets can also be fitted, without the need for tools. Two connection sockets are counter-sunk into the base of each, housing the plug connection and cable outlet so that they are safe against bending and secure. Cleverly placed handles facilitate the carrying of all M series loudspeakers in all situations. For a lifetime.
The M Series in Monitoring:
Only when the artist has acoustic control of everything “happening” on the entire stage can his performance also be correct! We are of the opinion that good monitoring is one of the secrets of success for professional PA companies, because this service is appreciated by the artist straight away!
That is why we have spent a lot of time on the M-series making sure that we are providing the sound companies, and also the artists themselves, with the best possible tool. Our prototypes are tested in live situations time after time in the formative phase and further optimised in the “laboratory” using scientific processes and adapted components.
The results keep on astounding even the "old hands": even sound distribution, low feedback, a pleasant listening situation, even at high volumes and with a direct “in-your-face” sound, are the main characteristics used to describe these speakers. Supported by the subwoofer B15, the M12 and M15 lend themselves to use as drum or side-fills with powerful output.
We have equipped the models M8, M12 and M15 with asymmetrical combination housings. As a mirror-symmetrical left-right pair they can also play the first violin or even contrabass, as wedges.
