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.
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.
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 m 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.
