The speaker system which collected the configuration
object of the foaming resin filling planar loudspeaker unit to the bookshelf system centering on the design way of the high fidelity play established by
HS-10000.
The foaming resin filling planar loudspeaker unit is adopted
as Woofers, mid ranges, and all the tweeters.
since an elastic-wave
radiation side is a planar, it is based on the hollow effect which it had the
flat frequency characteristic, was low-skew, and was not avoided in a cone form
-- it was filled and sound is banished.
Moreover, since [ which filled up
the rigid high metal cone with the resin ] a structure, there is little
distortion at the time of the Dainyuu power, and the extensive dynamic-range
property has been secured.
L-3005F which is a 30cm planar Woofer is
carried in low-pass.
It has a structure which filled up the rigid high metal
cone with the foaming resin, and the bass play is improved with the combination
of a large swing, high compliance and a gathered edge with high self-resonant
frequency, and a gathered spider.
Furthermore, a large-sized magnet with a
Lo-D actuator (low-distortion magnetic circuit) and a diameter of 140mm is
carried, and flat-ization of the low distortion and the impedance characteristic
is attained.
M-5001F which is a 5cm planar mid range is carried in the
mid range.
As a mid range, foaming resin filling was performed to the
diaphragm of the 5cm dome shape of a small caliber, and an expansion and
extensive dispersibility of a waveguide-plunger oscillating area are realized.
A gathered edge and the gathered Spider are adopted like a Woofer, fo is
lowered, and the relation with a Woofer is made smooth.
H-2001F which is
a 2cm planar tweeter is carried in the high region.
The way of filling up a
dome shape diaphragm with a foaming resin like a mid range is adopted.
The three-layer structure particle board of 30mm of board thicknesses by
the needle-leaf tree which used the Calah pine as the main material is adopted
as a baffle board and a back board.
Moreover, the appearance serves as
finish which harnessed grain.
