Description
 
The speaker system which carried out the flash rise and was born in order to raise the completeness of HLCompact 7ES-2 further.

The 20cm corn type Woofer is carried in low-pass.
The technology of RADIAL2 which hits the improved version of RADIAL adopted as L-Compact7ES-2 is supplied to this unit.
In RADIAL, after introducing molding equipments for exclusive use, a blend is changed for several sorts of polymer which has the optimal characteristic for each frequency band for polypropylene strong with a light weight in a base from the center to the circumference,Many problems generated on the corn surface in each zone were reduced.
The more natural performance in a flat has been obtained in RADIAL2, without sound causing distortion, even if the edge which was softly rich in contractility is adopted and a piston motion becomes large in order to pull out the performance to the maximum extent. In particular, the linearity at the time of the input of big power is improved. Moreover, the reflection which returns from edge to a voice coil by this is reduced, and the reproducibility of the high bandwidth of a unit becomes smooth and enables the still more detailed inside region play.

The aluminum hard dome shape tweeter of a 2.5cm caliber is carried in the high region.
ferrofluid 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 has been obtained by using a synthetic resin for edge.
Furthermore, a feeling of energy and a feeling of a spread of a high region are improved by equipping with an Open Weave grill of an establishment meter.

A network part is newly improved from each of parts, and re design by the computer-aided design system introduced newly is given. Furthermore, a final sound arrangement is determined by the listening test done by designer Alan Shaw's ear, and serves as a design which thought not only data but Hearing impression as important.

SuperTunedStructure which is Haar Beth's original design technique is adopted as enclosure. This studies behavior of the sound in enclosure thoroughly based on computer analysis, is the technology which tunes up the response of the enclosure which uses thin wood the optimal, and is aiming at the sound quality improvement.
Furthermore, bracing for internal strengthening of wood is eliminated and further improvement in the transit characteristic is aimed at by carrying out damping with bitumen (bitumen system).
Moreover, while lowering the resonance frequency of a port by setting up a bass-reflex port for a long time and improving a low-pass response, tuning of raising a feeling of power of inside compass is performed. Furthermore, the round baffle which stops the acoustic diffraction in a baffle end, and the technique of SuperGrille which attains optimization of sound wave propagation by embedding the grill of a jersey material at a front baffle are also adopted.

The input terminal serves as single connection specification corresponding to a gilding banana plug instead of bi-wiring connection specification.
