The NS-F901 offers beautifully designed speakers with an elegant piano finish. Capable of achieving transparent sound from data-rich, high resolution sound sources with excellent response, the NS-F901 speaker delivers musical excitement with outstanding expressiveness.

Soavo Concept: Delivering Natural Sound

Soavo speakers are created by Yamaha based on a long history and rich experience, including over 125 years of making musical instruments and more than half a century of making speakers. In order to reproduce high resolution sound sources with the highest quality, the NS-F901 features new speaker drivers that have undergone extensive sound quality tuning to further refine their expressive capabilities. You can be sure these speakers will deliver all the aural excitement that music and movies have to offer.

New A-PMD Midrange Reproduces High Resolution Sources with Rich, Clear and Detailed Sound

The NS-F901 adopts Yamaha’s unique new A-PMD (advanced polymer-injected mica diaphragm) with improved cone paper in order to reproduce high resolution sound sources. Taking advantage of the strong points of the A-PMD—extreme lightness, rigidity and stability—the speaker achieves smoothness, very fast response and sound with good dissemination, reproducing information-rich sound sources with an impressive feeling of density. The A-PMD incorporates a powerful magnetic circuit with a large neodymium magnet and a highly stiff aluminum diecast frame that increases the aperture ratio, achieving outstanding power handling and responsiveness in the mid frequency range - the heart of the music. The rubber surround, a spider made by Kurt Müller of Germany and meticulous tuning also contribute to the reproduction of high quality music and movie sound.

New A-PMD Woofer Provides Low Range Reproduction with Abundant Power and Responsiveness

The bass unit also 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.

Faithful and Natural High Frequency Reproduction Via an Aluminum Dome and DC-Diaphragm Equipped Tweeter

The 1” dome tweeter is made of aluminum for both hardness and responsiveness and like the midrange unit, 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 sources.

Built for Powerful, Accurate Sound Reproduction with an Innovative Cabinet Design

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 3-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.

Aluminum Tweeter Plate

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.

Carved Wooden Port

The wooden port is carved from high quality wood and has thick walls and a flared shape for smooth sound flow, low port noise and a spacious and massive bass feel.
