Features

Newly Developed Diaphragms Boast Acoustic Velocity
Comparable to That of Beryllium

NS-5000’s tweeter, midrange, and woofer all feature
diaphragms made of 100%* ZYLON® — a synthetic fiber created in Japan rated as
the world’s strongest** and boasting optimum elasticity — and vapor-coated with
Yamaha proprietary monel alloy. The soft-dome diaphragm suppresses peaks and
dips in the frequency response caused by the inherent resonance of the
diaphragm, while taking advantage of ZYLON’s high acoustic velocity comparable
to that of beryllium. The result is a remarkably flat frequency response, with
unified tone color and acoustic velocity over the entire frequency range,
providing a comfortable listening experience and meticulously accurate, superb
sound reproduction of the highest degree.

Newly Developed R.S. (Resonance Suppression) Chambers
Suppress Unwanted Resonance in the Mid and High Ranges

Mounted on the back of the tweeter and midrange speaker
units are newly developed R.S. Chambers (patent pending) that suppress
unnecessary tube resonance generated behind the diaphragm. Two specially shaped
tubes installed in accordance with our proprietary acoustic analysis cancel
tube resonance. These R.S. Chambers achieve higher-resolution audio
reproduction by eliminating the need for a large quantity of sound-absorbing
material inside the enclosure that tends to smooth the frequency response of
each speaker unit and might degrade minute nuances of the sound.

12″ 3-Way Bookshelf Design Draws on the Tradition of
the Legendary NS-1000M

As a result of meticulous research on a variety of enclosure
designs during the development of the NS-5000, we chose a bookshelf design as a
successor to the continuing legacy of the NS-1000M (released in 1974), the
pinnacle of Yamaha monitor speakers. This bass-reflex enclosure with an
internal volume of 65 liters — the smallest possible size for a 12″ 3-way
configuration — is solidly assembled with the 3-way mitered joint construction
technique and other traditional crafting methods. Reinforcing crosspieces
inside the enclosure, based on FEM analysis, suppress “box ringing” caused by
delayed vibration from the six surfaces of the enclosure. In addition, a
Twisted Flare Port prevents port noise (wind noise produced at each end of a
bass reflex port) inherent in the bass reflex design, and improves resolution
in the low frequency range while also enhancing signal-to-noise performance.

Carefully Crafted Laminated Plywood Enclosure Made of
Japanese White Birch from the Island of Hokkaido

In selecting a material for the enclosure of the NS-5000, we
carried out comprehensive studies of mechanical strength and acoustic
properties of various materials, as well as the quality of domestic wood
processed by painstakingly removing every knot and hole from the lumber and
ensuring the durability necessary to withstand long use; we settled on
laminated plywood made of white birch from the island of Hokkaido. The front
baffle is 1-1/8″ thick and the other five sides of the enclosure 3/4″
(in all cases, omitting paint primer layer and paint thickness), ensuring ideal
rigidity of the entire enclosure.

Newly Developed Acoustic Absorber Eliminates
Sound-Absorbing Material to Revive the Original Presence of the Music

The cuboid enclosure unifies internal standing waves at a
specified frequency, which are cancelled by a newly-developed resonance tube
(patent pending). This technology eliminates the previous need for the huge
amount of sound-absorbing material inside the enclosure. The result is the
virtual elimination of standing waves with amazing efficiency and pinpoint
accuracy—to energetically revive the essential presence of music, formerly lost
by sound absorption.

Glossy Black Piano Finish Provides Improved
Signal-to-Noise Performance—and Adds to the Luxurious Joy of Ownership

All six external surfaces of the enclosure have a glossy
black piano finish created using the same dedicated paint, primer, and
polishing processes used for renowned Yamaha grand pianos. The uniform and hard
membrane further increases the overall rigidity of the enclosure, and at the
same time it suppresses fine vibrations, contributing to the bright sound and
significantly enhanced signal-to-noise performance.

Frequency-Dividing Network

All drivers in the NS-5000 are connected in positive phase
with single wiring to deliver a natural, pleasing listening experience.
Components of its frequency-dividing network are mounted on a double-sided
printed circuit board with extra-thick copper traces of 140 μm in thickness; a
shorter signal path on the circuit board minimizes the loss of sound data
during transmission. Moreover, in order to minimize signal loss, we used for
the network handpicked parts of only the highest quality, such as the MCap
SUPREME EVO audio capacitor, which is made by Mundorf of Germany and renowned
as the pinnacle of audio-use capacitors, Mundorf’s MResist SUPREME attenuator,
and a woofer coil that weighs as much as 3.52 lbs.
