The Tallboy type speaker system which inherited the
technology cultivated with the monitor speaker technology of Pioneer, and
adopted the vertical twin scheme.
The vertical twin scheme which
allotted the Woofer up and down focusing on the tweeter and which is an in-line
coaxial placement double Woofer system is adopted.
Thereby, the sound energy
of two Woofers concentrates in the center, and it is in agreement with the axis
of a tweeter. For this reason, from a bass region to upper register, all the
sound comes to be reproduced considering a tweeter as a hub.
and phase response which were excellent as a result are realized.
20cm cone type Woofers which adopted the diaphragm laminated by the high polymer
film based on the cone currently used by TAD (Technical Audio Devices) are adopted as low-pass.
The AlNiCo-Magnet is adopted as a magnetic circuit.
The 3cm dome shape tweeter which used the new-materials ceramic carbon
diaphragm of 99.9% of the carbon purity is adopted as a high region.
AlNiCo-Magnet is adopted as a magnetic circuit like low-pass.
is mounted by the mid ship mounting scheme.
Each unit is fixed to the inner
baffle prepared in the interior of an enclosure in order not to tell the
unnecessary oscillation which a unit emits to a baffle.
thought of absent-resonance-izing is investigated and, as for the speaker frame,
the shielding is being firmly fixed by the backer.
Moreover, while making an
enclosure into a high rigidity, in order to suppress an unnecessary oscillation
of a top plate, the floating top is employed, a top plate is divided, and a
floating is carried out from an enclosure, and also the vibration level by
oscillation of a Woofer is sharply decreased through a damping material.
a baffle board uses the high-density particle board of 50mm of board
thicknesses, and a reflection of sound and diffraction phenomena are reduced by
considering it as the elliptic curve round baffle describing a big arc.
A network is constituting a circuitry for exclusive use to each of each
unit, prevents a mutual interference, and is reducing the transmit loss.
Furthermore, an OFC (oxygen free high conductivity copper) wire is adopted
as a choke coil or a product-line code, and the capacitor is also selecting
carefully and using the thing for sound for them.
interconnection which separates the cable for low-pass and the cable for high
regions, and supplies electric power is possible for a speaker termination.
Thereby, the tone quality is further raised because the
counter-electromotive force of a Woofer does not affect and carries out
influence to a tweeter.
The spike and felt which are properly used by
the floor which a flooring, a carpet, etc. install are attached.
