Yamaha Soavo NS-F901
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.
- New A-PMD midrange reproduces high resolution sources with rich, clear and detailed sound
- New A-PMD woofer provides low range reproduction with abundant power and responsiveness
- Aluminum dome tweeter with DC-Diaphragm and neodymium magnet
- Innovative cabinet design (non-parallel surfaces)
- 3-way mitered joint construction
- 2-chamber cabinet (woofer and midrange separated by slanted partition) with vertical bracing
- Highest quality parts including Solen capacitors in the networks
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.
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.
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.
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.
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.
