TAD | ET-703a | Super High Frequency Driver

The ET-703a is one of the world‘s most efficient and broadband reproduction loudspeakers for super high frequencies. TAD has fine-tuned the ET-703, known as a true rear compression type horn tweeter with this triple-slit fading plug. 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. The phasing plug is triple-slit type with slit spacing of approx. 5 mm, enabling reproduction up to 45 kHz. 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. The ET-703a will further revolutionize the world of digital sound monitoring.
