![]() ![]() This method ensures ideal phase equalization up to the ultra-high frequency areas. As a result, a wider reproduction bandwidth, excellent transient characteristics, and outstanding resolution are achieved.Ī rear compression type horn tweeter is produced by hollowing out the inside of the pole yoke to create a sound path and mounting the diaphragm from the rear. Furthermore, despite the large 35 mm diaphragm, the diaphragm is ultra-lightweight at 0.07 g, and the high resonance frequency is as high as 45 kHz. Using our unique vacuum evaporation technique, we have succeeded in integrating the surround and diaphragm with beryllium.īy designing the resonance frequency of the surround higher than 50 kHz, the negative effects on the audible frequency band are eliminated. ![]() ![]() The ET-703a will further revolutionize the world of digital sound monitoring.ĭiaphragm with integrated surround made of pure beryllium The magnetic circuit is provided by samarium-cobalt magnet that can ensure stable output even in high-temperature operation, and the magnetic flux density can reach 2 Tesla. 5 mm, enabling reproduction up to 45 kHz. The phasing plug is triple-slit type with slit spacing of approx. The 35mm beryllium diaphragm is extremely lightweight at only 0.07gr, and in synergy with the aluminum edge-wound voice coil insulated with an anodized aluminum coating film, combines outstanding response with a wide frequency bandwidth and high input power. TAD has fine-tuned the ET-703, known as a true rear compression type horn tweeter with this triple-slit fading plug. The ET-703a is one of the world‘s most efficient and broadband reproduction loudspeakers for super high frequencies. ![]()
