Designed to deliver live-sounding music reproduction, with full-range clarity and dynamic bass. Available with the same elegant Piano Black finish as Yamaha grand pianos. 2-way bass-reflex bookshelf speaker system for front channels Rounded top panel reduces vertical standing waves; trapezoidal cabinet shape reduces horizontal standing waves Advanced PMD cone woofer Aluminium dome tweeter with DC-Diaphragm™ Three-way mitered-joint construction The Design Is Innovative, the Sound Is Dynamic, Vivid and “Live” NS-700 speakers deliver sound that is so dynamic and vivid, it seems live. One of the main reasons for this is the nonparallel design of the cabinets. In designing them, the Yamaha speaker team aimed to maximise sound clarity and imaging, while minimising internal standing waves. They succeeded with a rounded top panel that helps to reduce vertical standing waves, and a trapezoidal shape that serves to reduce the horizontal ones. The result is a very natural, expansive sound, making the NS-700 speakers excellent for both multi-channel music of any genre and home theatre use. A-PMD Woofer and Midrange Cones Yamaha’s exclusive A-PMD (Advanced Polymer-injected Mica Diaphragm) cones are extremely light, rigid and sturdy thanks to the use of a low specific gravity material called PMP (Poly-Methyl-Pentene) that is much lighter than polypropylene. It provides very fast response time (sound rise and fall), as well as excellent midrange clarity and bass response. Outstanding internal loss characteristics decrease unwanted resonances to achieve the smooth frequency response that results in natural sounding vocals. Aluminium Dome, DC-Diaphragm™ Tweeter The high-performance 3cm (1-1/8”) tweeter features a dome made of aluminium, with Yamaha’s DC-Diaphragm that integrates the diaphragm and voice coil. It is extremely light yet durable, and transmits large amounts of sound information (highly detailed sound) for a denser sound field. As a result, this tweeter delivers highs that are crisp and clear at all power levels. Three-Way Mitered-Joint Construction for a Rigid Body Yamaha’s excellence in woodworking is used to good advantage in the three-way mitered construction of the cabinet joints. This technique ensures extremely tight joints so the entire cabinet behaves as a single unit, providing tight bass reproduction. Available in Piano Black Finish or Brown Open Pore Finish Cabinets feature a luxurious, environmentally friendly open-pore finish. The Piano Black Finish is made with the same materials, and using the same application process, as is used on Yamaha's finest grand pianos.
