|145,000yen(one set, the 2003 release)
The speaker system refined by technology exchange
with the engineers of BBC while inheriting the musicality of HL Compact and HL
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.
hard dome shape tweeter of 2.5cm is adopted as a high region.
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.
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.
