The MR18REX/XF is a midrange coaxial loudspeaker providing high quality sound in a very
compact format.
The cone of the midrange acts as a horn loading for the tweeter, and the chassis of the dome unit represents the throat of this horn.
The coaxially arranged precoated fabric dome high frequency unit has a smooth frequency response, and integrates with the cone driver to a point source. Voice coil windings immersed in magnetic fl uid increase short term power handling capacity and reduce the compression at high power levels.
The pre-coated reed-paper cone acts as a piston throughout the recommended frequency range.
The completely new rubber surround reduces resonances and prevents surround break up in the midrange band. The surround's small inverted roll, combined with a profi le that follows the shape of the cone, results in almost total elimination of diffraction effects on the tweeter's output.
