Description
 
The speaker system born by adding improvement to HL-P3ES.

The polypropylene corn type Woofer of an 11cm caliber is adopted as low-pass.
A 2.5cm aluminum voice coil is adopted and it is mounted by the die-casting chassis. Moreover, the low loss material is used for edge.

The hard dome shape tweeter which used the aluminum diaphragm of a 1.9cm caliber is adopted as a high region.
ferrofluidド cooling processing in which the play capability stabilized by the application of magnetic oil also at the time of high temperature could be held was performed, and more exact reproducibility is gained by using rigid resin for edge.

The same technology as LS3/5a is supplied to the network design, and also the original technique of elaborating smoothness on Hearing impression by repetition of the audition which valued the reproducibility of man's voice is used.
Optimization of the power response on the phase characteristic in near a crossover point or an axis is attained by arranging a low-pass unit back more slightly than a tweeter.

The speaker terminal has adopted the thing corresponding to a banana plug, and also bi-wiring connection is possible for it.

Enclosure carries out analysis and trial and error, spending much time on damping of wood at and tuning of a response, and is pursuing the ideal of a small speaker. Furthermore, behavior of the sound in encapsulated type enclosure is based on computer analysis, and it is a history of research,SuperTunedStructure used as the base of the enclosure design is inherited, and it is designed by middle size systems, such as HL Compact 7ES-2.
The baffle has taken in the technique of SuperGrille which attains optimization of sound wave propagation by having adopted the round baffle which stops the acoustic diffraction in an end, and also embedding the grill of a jersey material at a front baffle.
The exterior serves as cherry finish.
