The first SR-Λ (lambda) series was introduced 30 years ago, and now (Sep 2010) the SR-407 has accomplished further evolution with its new sounding body (sound element). The conventional sound element has employed simplest structure so that the widest possible film diaphragm area can be effectively used in comparison with its external size. Taking advantage of the conventional feature, the new sound element has been packaged in a tough resin case. Thus the new sound element has cleaner sound and more accurate sound image.
Also, the new thin-film material are almost free from stretch from temperature or humidity, enabling both the rich, deep low-frequency and delicate high-frequency sound.
Low capacity wide adoption: SR-407 employs a wide range of special low capacitance cables which means that there is the tiniest loss of signal from the driver unit/amplifier to the earspeaker.
