SC-E757
Commentary

This speaker system was developed using European technology for key materials and sound production techniques with the aim of reproducing sound rich in musical quality in speaker systems.

A 14.5 cm CSC (Composite Sandwich Cone) woofer is installed in the lower range.
The diaphragm of this unit is laminated with two different types of PP materials excellent in both rigidity and internal loss, making it possible to adhere PP materials, which has been considered scientifically difficult so far, and has achieved excellent frequency response and signal reproduction capability.
In addition, the rear window is set as large as possible to minimize the mutual interference of back pressure, and the newly developed flat damper provides linear restoring force, so that excellent power response can be obtained from high volume to low volume playback.
In addition, the inverted anti-reflection dust cap reduces distortion caused by end-face reflection of the edge.

A constant directional WA (Eide Angle) dome tweeter is installed in the high range.
The front plate with a slight inclination controls the wave front of the sound, reducing the difference between the frequency response of direct sound and that of reflected sound, and acquiring more natural sound image localization and sound field feeling.
In addition, this front plate controls the anti-resonance of the diaphragm edge, and together with the soft dome, excellent frequency characteristics are obtained.

It is an anti-magnetic type without magnetic leakage to the outside, and does not have any effect even if it is installed near a TV or image display.

The enclosure is finished through the same process as a grand piano.
By repeating painting and polishing in dozens of steps, the paint film is not only beautiful in appearance but also has excellent hardness, which improves sound propagation speed.

There was a speaker stand that was sold separately and had the same process as the enclosure.
