Prestige MR18REX/XF - H1699-08/06 7" Coaxial Woofer
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.
Highlights
- Long term power handling (RMS) is 80 Watts (Woofer) and 90 Watts (Tweeter)
- The coaxially arranged precoated fabric dome high frequency unit has a low resonance frequency and integrates with the cone driver to a point source
- The pre-coated reed-paper cone acts as a piston throughout the recommended frequency range

Seas Prestige MR18REX/XF - H1699-08/06 7" Coaxial Woofer
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 fluid 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 profile that follows the shape of the cone, results in almost total elimination of diffraction effects on the tweeter’s output.
