![]() "We can hear everything we measure, but we can't measure everything we hear. Maximum output sound pressure levelđ20dB/mĭimensions Width 660x height 798x depth of 614mm Using unit etc.ğor low-pass: 40cm cone type (TL-1601a)įor high regions: Horn type (TD-4001+TH-4001) SchemeĒ ways, 2 speaker bass-reflex scheme, and a bookshelf type Reinforcement of frame structure effective for this was added, and sufficient intensity is secured. High-rigidity-ization is attained by adopting apitong plywood as an enclosure. 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. 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. TN-2 which is a dividing network of TAD is adopted as a network. Furthermore, the large listening area is secured by realizing the directive effective pattern obtained from actual sound field research. ![]() 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. 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, 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.ĭriver unit TD-4001 and horn TD-4001 are carried in the high region. 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.įurthermore, 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. TL-1601a of a 40cm cone type Woofer is carried in low-pass. 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. ![]() I would love a pair of these babies from the 80's:
