A professional studio monitor speaker system developed for editing and a small control room using TAD (Technical Audio Devices) units.

A 40 cm cone woofer TL 1601 a is installed in the low range.
High efficiency has been achieved by combining a magnetic circuit using an alnico magnet with a lightweight vibration system, and by thoroughly improving the initial motion sensitivity of the vibration support system.
In addition, in order to improve the durability required for professional use, it is compatible with the coupling of a vibration support system with smooth movement and a special aging cone that adheres to the concept of DRS (dynamic response suspension).
Combined with a highly heat-resistant voice coil and an efficient heat radiation design, Dainyu Chikara has obtained excellent durability even in long-term use.

The driver unit TD 4001 and horn TD 4001 are mounted in the high range.
The TD 4001 uses an Alnico magnetic circuit with a magnetic flux density of 20,000 Gauss and a large beryllium diaphragm with a diameter of 10 cm to realize wide-band reproduction of 600 Hz to 20 kHz.
The TH-4001 is a stabilized dispersion horn developed to demonstrate the capability of the TD-4001. It has succeeded in improving the directivity at 10 kHz or higher, which was considered difficult with conventional large horns. Moreover, by realizing an effective pattern of directivity obtained from actual sound field research, a wide listening area is ensured. It is made of Painted maple.

TN-2, a TAD dividing network, is used for the network.
By using OFC (oxygen-free copper) for the wiring cord and choke coil winding, press-join-type connection using OFC sleeve, large gold-plated terminal and high-quality condenser, we have realized low loss and low leakage.
In addition, the LF circuit is made into a balanced circuit to eliminate the leakage caused by the ground line, and the HF circuit and LF circuit are separated to eliminate the noise turbidity at the crossover. This is a custom design that brings out the performance of each unit.

The enclosure is made of Apiton plywood for higher rigidity, and the frame structure is reinforced to ensure sufficient strength.
