Yamaha NS-B901

These demure bookshelf speakers are possibly considered the 'Baby' of the 901 Soavo series. But don't let these small but elegant speakers deceive you - they have been designed to deliver superb surround sound, and these speakers strikingly bold design matches the audio performance which reveals all the realism of high resolution audio sources. The design of the cabinet is of course extremely important if the aim is to create a speaker with superior reproduction capabilities. The goal was to reduce standing waves to ensure highest accuracy, as well as to provide a full, three-dimensional sound with an awesome feeling of depth. The solution was to design a cabinet with non-parallel surfaces, having the woofer and midrange sections divided by a slanted partition, and strengthening the entire enclosure with vertical ladder bracing. Another important point is the three-way mitered construction of the cabinet joints, achieved thanks to Yamaha’s excellence in woodworking. This technique ensures extremely tight joints so the entire cabinet behaves as a single unit, providing tight, powerful and accurate bass reproduction. The crossover networks employ the highest quality parts, including Solen metalized polypropylene capacitors and large iron-core coils with carefully selected wire. All parts are connected by directly soldering each one individually, instead of using printed circuit boards, further contributing to the rich and vivid sound. Finally, meticulous sound tuning ensures optimum transitions between drivers for smooth and natural sound across the entire frequency range. A diecast aluminum tweeter plate isolates the tweeter from cabinet vibration and provides a solid attachment for the tweeter unit. This prevents incidental movement, helping to ensure that the high range sound is clear and transparent, with no coloration. The 13 cm (5”) woofers adopts the new A-PMD with a paper cone upgraded for the reproduction of high resolution sound. The use of a large ferrite non-shielded magnet ensures high drive power that provides prodigious bass volume. By utilizing high quality parts such as a high rigidity aluminum diecast frame that dampens resonance, it reproduces bass with a deep sense of scale, achieving both power and speed, leaking out of the speaker cone. This means the full power of the waves is forced out through the air port, resulting in clear, powerful bass. The 3 cm (1”) dome tweeter is made of aluminum for both hardness and responsiveness, uses a neodymium magnet. It delivers sound that links the medium and high ranges with natural smoothness and transparency. Firmly integrating the diaphragm and voice coil and using a thick surround material increases the sound density and resolution in the high range. With a heavy aluminum diecast tweeter plate that minimizes unwanted resonances and an extremely fine mesh grill that provides ideal sound dissemination, it faithfully reproduces dense sound atmospheres and nuances from high resolution sound source. The NS-B901's are perfect to complete your home cinema system as dynamic surrounds in a multi-channel set up, or are equally at home with one of Yamaha's fantastic integrated stereo amplifiers. Whatever the source material or application, these stunning looking speakers will ensure high-resolution sound reproduction that will deliver pure audio enjoyment.
