Description
 
The speaker system refined by technology exchange with the engineers of BBC while inheriting the musicality of HL Compact and HL Compact 7.

The 20cm corn type speaker unit which adopted the RADIAL corn is adopted as low-pass.
This corn is reducing many problems generated on the corn surface in the zone of inside low-pass and each mid-high range by optimizing the amount of combination of aluminum, and also changing the amount of blends from the center of a diaphragm to the circumference, employing the merit of polypropylene efficiently.
Furthermore, in HL Compact 7ES-2, in order to raise reproducibility more in compact enclosure under cooperation with BBS engineers, the polish is further applied to the RADIAL corn.

The hard dome shape tweeter of 2.5cm is adopted as a high region.
Aluminum is adopted as the diaphragm and the input-proof [ high ] design is performed.

Top quality parts including the fiberglass board of a computer grade are selected carefully and used for a network.
Every one circuit setting up was finished is tested by computer, and after it prepares matching and it repeats an audition, it is mounted.
Bi-wiring connection is possible for a speaker terminal, and it also supports the banana plug.

Enclosure is the design which follows the tradition of BBC and a front and a rear baffle can remove, and forms a big joint structure of a loss.
Moreover, by considering it as the sandwich construction which makes several materials from which Resonance and a stiffness differ between materials with high hardness stratify, it pressed down by neither weight nor rigidity, but the vibration is dumped with the physical properties and combination of the material itself.
Furthermore, Super Tuned Structure is adopted. This is the technology tuned up using computer analysis, and has eliminated the unnecessary vibration of inside compass by this so that a thin material can react to the energy of sound quickly.
Moreover, the edge of a front baffle is carrying out round processing, and is reducing the acoustic diffraction in edge.
The grill of a jersey material is embedded in the slot of a front baffle, raises a sense of togetherness with enclosure, and is attached by the technique called SuperGrille which suppresses the influence on sound quality.
It is the design which it not only protects a driver unit, but carries out the listening of the sound wave radiation in the state where it usually equipped, with the grill prepared smoothly.
The exterior serves as teak finish.
