The professional studio monitor speaker system
developed as the small control room which adopted the unit of TAD (Technical
Audio Devices) and was developed, or an object for an edit.
a 40cm cone type Woofer is carried in low-pass.
The high efficiency is
realized by having raised thoroughly the magnetic circuit of an AlNiCo-Magnet
using, the combination of lightweight vibration system, and the initial shock
sensitivity of an oscillating supporting system.
Furthermore, in order to
improve the endurance demanded as an object for pros, it corresponds by coupling
of the smooth oscillating supporting system of a motion which pierced through
DRS (dynamic response suspension) thought, and a special aging cone.
Moreover, the endurance excellent also in the using of the Dainyuu power
long time has been conjointly acquired with the heat-dissipation design with the
sufficient voice coil of high heat resistance and efficiency ratio.
Driver unit TD-4001 and horn TD-4001 are carried in the high region.
TD-4001 has realized the wide band play (600Hz - 20kHz) by adoption of the
Alnico magnetic circuit of flux density 20,000Gauss, and 10cm in diameter a
large-sized beryllium diaphragm.
Moreover, TH-4001 is the stabilized
dispersion horn developed in order to demonstrate the capacity of TD-4001, and
has succeeded in the directive modification by 10kHz or more made difficult in
the conventional large-sized horn. Furthermore, the large listening area is
secured by realizing the directive effective pattern obtained from actual sound
field research. The acer mono is used for the material.
TN-2 which is a
dividing network of TAD is adopted as a network.
OFC (oxygen free high
conductivity copper) was adopted as the product-line code or the choke coil
coil, and thorough low-loss-izing and reduction in a leakage, such as connection
of a press join type, a gilding large-sized terminal, adoption of a quality
capacitor, etc. which use an OFC sleeve, are realized.
Moreover, making HF circuitry and line feed character circuitry separate
etc., in order to form line feed character circuitry into a balance circuit
in order to remove the inter leakage resulting from an earth line, and
also to sweep away muddiness of the sound in a crossover is the custom-made
design which demonstrates the performance of each unit.
High-rigidity-ization is attained by adopting apitong plywood as
an enclosure. Reinforcement of frame structure effective for this was added, and
sufficient intensity is secured.
