Yamaha created the NS-600A bookshelf speaker by fusing rich aesthetics with the latest advanced technology. The unique diaphragm material produces exceptionally unified tone, while the spacious large-capacity cabinet delivers a vast and luxuriant sound field. It is all topped off with a beautiful grand piano-like finish that gives you an even more luxurious music listening experience.
The NS-600A is a compact 2-way speaker that provides faithful reproduction of all musical instruments and precise sound images.
TRUE SOUND
Yamaha is the only audio brand in the world that manages every facet of sound, from its creation to the moment it graces your ears. Simply close your eyes, and you won't just hear the music - you'll experience the unparalleled sensation of being genuinely closer to the artist.
TONAL BALANCE
Every ear hears the world differently. Yamaha expresses sound as the artist intended. Reproducing sonic elements such as vocals and instruments at the right pitch requires both passion and precision. Yamaha accomplishes this through tonal balance, enriching harmonies and recreating musicality to help you hear sounds you couldn't hear before.
PERFECTLY UNIFIED TONE
As a world-renowned music brand, Yamaha is relentlessly committed to accurately reproducing the sounds of instruments. In order to make this quest a reality, we created flagship speakers under the design concept of having consistent tone color throughout the entire frequency spectrum and applied unique technology to achieve it. For each and every one of its speaker units, the NS-600A employs the newly developed Harmonious Diaphragm™—made from a blend of ZYLON®, which has excellent sound velocity and optimal internal dissipation — and spruce, which is used in the soundboard of Yamaha grand pianos.
DYNAMICS
We pursue a sense of dynamics that express the contrast between stillness and motion in the music - allowing you to immerse yourself in the deep emotions in the music.
TOTAL MUSIC REPRODUCTION
Our patented Resonance Suppression chambers are mounted on the back of the tweeter in order to faithfully express even the finest nuances of musical instruments and voices. Two specially shaped tubes cancel unwanted resonance generated behind the diaphragm, revitalizing and maintaining the original sound.
FAITHFUL MUSICAL PRESENCE
Conventional speakers use a large amount of sound-absorbing material to eliminate standing waves inside the cabinet. However, this also removes much of the music's character. In the NS-600A, we’ve employed our patented Absorber tube to eliminate standing waves, while minimizing the amount of absorbing material, so that the original realism of music is reproduced with full energy and dynamism.
SOUND IMAGE
The position of the artist and instruments, along with the delicate nuances and atmosphere of the performance space, are stunningly reproduced. The resulting sound is so lifelike, you'll feel as though you were in the same room as the performance.
HIGHLY MUSICAL VIBRATION CONTROL
The principles for creating superb sound — understanding enclosure acoustics and pinpointing where to suppress vibrations — are virtually identical, whether crafting musical instruments or speakers. The NS-600A's cabinet construction incorporates state-of-the-art design technology while making full use of laser vibrometers, a tool essential in musical instrument research and development, as well as sophisticated Finite Element Method (FEM) analysis. The cross piece of the cabinet has also been reinforced. Experience a rich spatial sound that fully immerses you, making you feel as though you're right in the center of the performance.
SEAMLESS SONIC PERFORMANCE
Representative of the flagship series, the NS-600A adopts the highest quality parts for the crossover circuit. The MCap® SUPREME Classic audio capacitor made by Mundorf of Germany, renowned as the pinnacle in audio-use capacitor, is used along with a huge woofer coil.
TWISTED FLARE PORT
The speaker is equipped with our original Twisted Flare Port. It adds a gentle twist to reduce air flow noise around the port, a common problem in conventional bass reflex speakers. This delivers an exceptionally accurate response with clear, tight bass reproduction.
HIGH-QUALITY FEEL
The speaker terminals feature an original design, with a shape that comfortably fits with human fingers for a luxurious feel, while simultaneously allowing for effortless tightening.

Buying a Yamaha Factory Refurbished product is a great way to get "as-new" products at a considerable savings. Every product has been thoroughly tested, repaired (if necessary), cleaned and otherwise renewed to original condition. Next it's repackaged with original accessories included. When you consider that a factory-renewed Yamaha product undergoes such close scrutiny for defects and workmanship, you might actually be buying something that is in many ways better than new. And for your piece of mind and protection, your purchase is covered by a full 1 year parts and labor warranty valid at any authorized Yamaha repair center (you can look-up locations online here or call 714-522-9888)
Yamaha, like all electronics manufactures, receives products returned for various reasons. In 2023 consumers returned 23 billion dollars in electronics globally, of which less than 5% were found to be defective! Once a product has been opened, it must be resold as refurbished or open box and cannot be resold as new again. The history and reason why a product was returned is not provided to us, thus we cannot provide any additional details regarding its past. All products are processed by Yamaha certified technicians, where they are fully tested, repaired (only if necessary), and retested again to ensure the highest quality control. Each unit must pass a complete battery of test before it can be titled a "Yamaha Factory Refurbished" product.
Most (not all) units are cosmetically in Mint Condition (graded a 9 or higher on a scale of 1-10). Very minor signs of wear (light surface scuffs or minor scratches) may be present, although most units show little or no signs of any usage. We DO NOT sell products that are cosmetically damaged (cracked displays, broken knobs, heavy scratches, or physically abused) unless noted in the description. Unfortunately, we cannot provide actual photos of each unit or pick the best one for anyone, as they are all randomly chosen from our factory sealed boxes.
