A Modern Classic

Introducing our flagship 3-way bookshelf speaker system, setting a new standard in performance and quality by which all other Hi-Fi speakers should be judged.

  • Newly developed diaphragms boast acoustic velocity comparable to that of beryllium
  • Newly developed R.S. (Resonance Suppression) Chambers suppress unwanted resonance in the mid and high ranges
  • 12″ 3-way bookshelf design draws on the tradition of the legendary NS-1000M
  • Carefully crafted laminated plywood enclosure made of Japanese white birch from the island of Hokkaido
  • Newly developed Acoustic Absorber eliminates sound-absorbing material to revive the original presence of the music
  • Glossy black piano finish provides improved signal-to-noise performance — and adds to the luxurious joy of ownership
  • Frequency-dividing Network

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.
