this unit uses an l. T. P edge (linear travel piston edge) with moderate flexibility to lower the lowest resonance frequency and reduce distortion. In addition, by suppressing the reflection of sound waves from the edge or from cone paper due to amplitude, the disturbance of frequency characteristics is reduced.
the 13 cm cone type skoker is mounted in the middle area.
this unit uses white cone paper with a new lightweight material on the edge and a back cavity to reduce interference with the woofer.
a 5.4x6.1 cm tweeter is installed in the high range.
the sound quality is enhanced by a powerful magnetic circuit and a full-scale equalizer.
a 7.5 cm cone type super tweeter and two dome type super tweeters with a unit diameter of 8.3 cm are installed in the super high band.
the newly developed dome tweeter improves the directional characteristics over a wide area.
the front baffle has ivory white nylon hair planted on the surface of the plywood to enhance the sound absorption and eliminate the muddy sound. In addition, the front grill net can be removed by the magic tape.
the enclosure is made of a combination of homo gen and lauan plywood with reinforced beams to reduce box rumbling, and the exterior has a walnut oil finish.
level controls are provided for the mid-range and high-range signals.
in addition to the general speaker terminal, there is a jack type terminal.
