A 2-way bass-reflex library type, the Yamaha NS-600A are built around a 30 mm dome tweeter and a 16 cm midrange-woofer, both equipped with the new Zylon Harmonious Diaphragm cone. More compact than their elders NS-5000 (3-way bass-reflex) and NS-3000, the Yamaha NS-800A loudspeakers have obviously benefited from all the know-how of the brand's engineers.
Yamaha NS-800A, main technical characteristics
Many of the technologies embedded in the NS-800A are directly derived from those developed for the NS-5000/NS-3000. For example, an original acoustic absorber tube whose purpose is to reduce the impact of internal standing waves while minimizing the volume of material required.
For the rest, there are loudspeakers based on the original Harmonious Diaphgram membrane, a mixture of Zylon and spruce, for a perfect transition between low, mid and high frequencies. Similarly, there is an RS chamber (see photo above) located at the rear of the tweeter to suppress the resonances of the tube which can cause a forced displacement of the speaker membrane, therefore a sound degradation. Finally, the Yamaha NS-800A naturally benefit from components selected for their performance, for example Mcap Supreme Classic capacitors made in Germany by the company Mundorf.
We can also mention a twisted vent (see photo above) to reduce airflow noise, a recurring concern of bass-reflex speakers. Plus statutory screw terminal blocks.
Yamaha SPS-800A, high foot optional
Namely, Yamaha has developed the Yamaha SPS-800A stands (€699) specifically for the NS-800A speakers. These allow listening, in a seated position, at ear height in addition to minimizing the audio reflections that are irremediably present on a support such as a shelf or tray. These come with decoupling spikes.
Availability announced, in black lacquer (piano lacquer), for the month of August. Indicative prices: €4,198 per pair.
