NS-700X
Release
d in 1986, Yamaha¡¯s NS-700X charged straight to the forefront of the popular price speaker class, its major selling point being its dome tweeter¡¯s ion plated amorphous diamond diaphragm that achieved a hardness comparable to that of diamond. This diaphragm was touted as taking advantage of Yamaha¡¯s unique LSI manufacturing technology, with catalogs saying, "The use of a high voltage ion acceleration gun to embed carbon atoms on the surface of the titanium that forms the diaphragm base allows the generation of an amorphous layer of high hardness," and with the same material used in the cone midrange¡¯s center cap it was solidly aimed at high-fidelity playback from digital sources. The woofer utilized a high rigidity twin pure carbon cloth cone featuring two sheets of woven carbon cloth fixed at a 45 degree angle relative to each other. With a diameter of 31cm, its twelve fixing bolts were rarely seen in high-grade machines and certainly caught the eye. While meeting the requirements of a popular price speaker, the NS-700X gained a reputation for producing high-quality sound. But after just this model Yamaha withdrew from the popular price front lines and soon introduced to the world a new speaker completely opposed to the doctrine of "quantity."
