Seas H0487-08/06 MP14RE/XF is a well known high power Seas Midrange/Tweeter Co-axial unit with a 5" polypropylene cone and a 26mm neodymium tweeter giving full range response with a suitable woofer.
Frequency Response ( with suitable crossover) 3000Hz - 25,000 Hz.
This loudspeaker is a coaxial and time coherent arrangement of a cone midrange unit and a precoated fabric dome high frequency unit. The cone of the midrange unit acts as a horn loading for the tweeter, and the chassis of the dome unit represents the throat of this horn. Unlike most traditional coaxial loudspeakers, this arrangement has two advantages:
1. The two drive units have identical acoustic centers
2. Their directivities in the crossover frequency region are practically identical. With a symmetrical woofer arrangement, e.g. one woofer above and one below this unit, it is possible to build coherent loudspeakers with a symmetrical and stable radiation pattern combined with a smooth frequency response.
The midrange unit has an injection moulded metal chassis for strength and stability. The polypropylene cone is carefully matched to a high loss rubber surround. The large voice coil diameter (39mm) allows efficient heat transfer for stable voice coil temperature.
The high frequency unit has a vacuum formed, precoated fabric dome diaphragm, with its voice coil immersed in magnetic fluid for improved heat transfer and damping. A small, efficient magnet made from neodymium-iron-boron provides the magnetic field
