Main features

(1) Graceful design in ROSE GOLD, the exclusive color for the 80th Anniversary Model

The model features a graceful design with TAD's brand plate and speaker trim rings decorated in ROSE GOLD, which is the exclusive color for the 80th Anniversary Model, along with the nameplate on the back of the speaker featuring the words "80th Anniversary Model". Moreover, it adopts ultra-small baffles that minimize acoustic diffraction and an enclosure carefully hand-painted in piano black finish by skilled craftsmen, from the spraying of the coating material, polishing of the base paint, to the final polish. The 80th Anniversary Model speaker stand is also coated in piano black finish which is the same color with the enclosure.

(2) 9-cm CST driver achieving excellent stable sound localization and a natural sound field space

Featuring the compact 9-cm CST driver developed by TAD to reproduce natural sounds, it has pursued the point sound source concept. The mid-range and tweeter are arranged coaxially to homologize their directional characteristics and exclude acoustic disturbance. At the same time, the tweeter features a highly rigid, light-weight beryllium diaphragm. These properties deliver highly stable sound localization and natural sounds in a wide range, from 420 Hz to 60 kHz.

(3) 16-cm MACC*3 diaphragm woofer for improved linearity and optimized driving force

The 16-cm woofer adopts a MACC diaphragm with enhanced strength and low internal loss for ideal vibration characteristics, as well as a magnetic circuit with outstanding linear drive characteristics. This diaphragm is constructed of aramid fiber and nonwoven fabric separately formed then laminated, achieving rich bass tones with excellent linearity and clear mid-range tones free from coloration.

(4) Bi-Directional ADS Ports for natural and rich bass sound

With slit-shaped ports positioned on the enclosure's side panels with front and back openings and a flared-shaped section leading to the opening, the Bi-Directional ADS ports work smoothly and efficiently. The symmetrical front-back, left-right layout eliminates unnecessary sound from the port and the influence of internal standing waves, producing rich and powerful bass sound.
