Yamaha NS-5000 Left Bookshelf Speaker Piano Black

Introducing Yamaha’s flagship 3-way bookshelf speaker system, setting a new standard in performance and quality by which all other Hi-Fi speakers should be judged. 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's 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 comfortable listening experience and meticulously accurate, superb sound reproduction of the highest degree. 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 the 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. As a result of meticulous research on a variety of enclosure designs during the development of the NS-5000, 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 30 cm (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. 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 in thickness; a shorter signal path on the circuit board minimises the loss of sound data during transmission.
