The M12C coaxial series loudspeaker is fitted with a coaxial cone transducer. It features a coaxial point source in the transducer unit structure. This eliminates phase differences between high and low frequencies .And it provides no distortions due to distance and time differences among source points .Driven by the coaxial structure, the sound spreads in perfect sonic symmetry.
