A 38 cm cone woofer is installed in the low range. This unit uses a L. T. P (Linear Travel Piston Edge) edge with moderate flexibility to lower the lower resonance frequency and reduce distortion. In addition, by suppressing the reflection of sound waves from the edge or from the cone paper due to the amplitude, the disturbance of the frequency characteristics is reduced. The 13 cm cone skoker is mounted in the central 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. In the high range, a 5.4x6.1 cm tweeter is installed. The sound quality is improved by a powerful magnetic circuit and a large-scale equalizer. The super high band features a 7.5 cm cone super tweeter and two dome super tweeters with a unit diameter of 8.3 cm. The newly developed dome tweeter improves directional characteristics over a large area. The front baffle features ivory white nylon hairs planted on the surface of the plywood to improve sound absorption and eliminate muddy sound. In addition, the mesh of the front grille can be removed with a magic tape. The casing is made with a combination of Homo gen and Lauan plywood with reinforced beams to reduce the rumble of the case and the exterior is finished with walnut oil. Level controls are provided for mid and high range signals. In addition to the general speaker terminal, there is a jack terminal.
