en.Wedoany.com Reported - Yamaha has released the NX-70A wireless stereo speakers, marking the company's return to this category after more than a decade. The speakers feature a two-way design, are part of the MusicCast ecosystem, and come equipped with wired connectivity, an acoustic calibration system, and several proprietary technologies.

The Yamaha NX-70A is presented as a bookshelf speaker, measuring 189 x 234 x 333 mm, with the main speaker weighing 5.7 kg and the secondary speaker 5.4 kg. Its design features a pointed arch silhouette, a sloped top panel, and a stylized ventilation grille, evoking an Art Deco aesthetic. The color scheme is primarily black and white, accented with a few bronze elements. A small monochrome screen is hidden beneath the glossy black surface (only on the main speaker).

Both speakers are active and equipped with independent amplifiers, with all ports and the smart core located on the main speaker. Interconnection is achieved via lossless low-latency wireless connection or an RJ45 Ethernet cable.

In terms of connectivity, the speakers support AirPlay 2, Spotify Connect, TIDAL Connect, Google Cast, and Roon Ready. A dedicated app controls the speakers and enables the YPAO acoustic calibration feature. This function analyzes the acoustic response at the listening position using a microphone connected to the main speaker and adjusts sound processing accordingly. Wired interfaces include 1x HDMI eARC, 1x optical port, 1x 3.5 mm audio input, 1x USB-A (for local file playback), and 1x RCA subwoofer output.

Each speaker is equipped with a 3 cm large-diameter tweeter and a 13 cm mid-bass driver. The diaphragms are made from a blend of Zylon fiber and spruce fiber; Zylon is stronger than Kevlar, while spruce is commonly used for the soundboards of grand pianos. The speakers also feature Synergistic Drive technology, which optimizes the synergy between the amplifier circuit and the speaker drivers.

Regarding amplifier power, each mid-bass driver delivers 100 W, and each tweeter delivers 60 W. The frequency response is 50 Hz to 35 kHz (measured at -10 dB).

The Yamaha NX-70A will be available in July, priced at €2,999. Optional stands are available for €599 (per pair).
