YAMAHA NS 690 V.1 Version 1 means, you can bi/ tri-amping these babies. 3-Way Bookshelf Loudspeaker System (1977-83) Except for the NS-670 woofer, which used the JA-2501A, an improved model for the NS-650, the NS-690 and NS-670 speaker units were completely redesigned, establishing the technologies that became standard in Yamaha speakers like a large ferrite magnet and copper ribbon wire edgewise-wound voice coil woofer, a tangential edge molded soft dome midrange with a back cavity packed with sound absorbing material to lower the FO (lowest resonance frequency), and a soft dome tweeter integrating the voice coil bobbin and diaphragm. The midrange and tweeter were made of an original double-coated material made up of a base of thermoplastic resin on fabric serving mainly to maintain the shape and viscoelastic rubber-based resin acting primarily to dampen resonance. As well as becoming the standard for later Yamaha soft dome units, it was also used in elements such as the NS-1000M woofer edge. An aluminum diecast frame made using Yamaha’s alloy technology was adopted in all units, and its metallic feel combined with a mechanical structure was highlighted in comparison with the natural texture of the wooden exterior design to give the Yamaha speaker what could be called an all-new identity. In combination with the CA-1000 Integrated Amplifier on sale at the same time, the delicate, natural tone of the NS-690 made it a smash hit for its "European sound" unavailable in conventional domestic systems.
