The professional studio monitor speaker system for
large-sized control rooms which adopted the unit of TAD (Technical Audio
Devices) and was developed.
Two TL-1601a of 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.
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.
TD-4001 and horn TD-4001 are carried in the high region.
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
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-1 which is a dividing network of
TAD is adopted as a network. Since this TN-1 is designed for the twin drive, it
is a 4-ohm specification.
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.
