The speaker system which adopted the material
original with an old enclosure and realized clearer and high-definition sound in
order to refine the tone quality of 4312 serieses further.
is a 30cm cone type unit is adopted as low-pass.
The SFG magnetic circuit original with low distortion JBL is adopted as a magnetic circuit. The cone paper coated [ the special reinforcing material ] is adopted as a diaphragm. And the clear bass whose dumping was effective is gained.
Moreover, rigidity is raised by adopting aluminum die-casting as a frame.
104H-3 which is a 13cm cone
type unit is carried in the mid range.
035Ti which is a pure titanium
tweeter is carried in the high region.
Pure titanium was molded into the
precision dome of 25micro thickness, and the skillful tone quality is realized
in combination with the diamond edge suspension aiming at the improvement in a
high region property, and the rib pattern which prevents a splitting
The Attenuator which can control each of a mid range and a
high region is carried.
The enclosure laminated the high-density
material "reaction mall dead form" original with JBL which has the vibration
suppression effect excellent in front particle board first, and has dumped the
unnecessary oscillation of the whole enclosure.
Furthermore, in order to
decrease a primary reflection of the play sound on the top layer of a baffle
which had had a delicate ill effect on the stereo image, the "neo plane form" is
adopted as the perimeter of a unit, and the tone-quality failure by the primary
reflective sound in a mid-high range is especially made into the minimum.
Moreover, there were two kinds of finish, walnut finish and black finish.
