In detail

About the NX-70A

Overview

The Yamaha NX-70A is a pair of powered wireless hi-fi speakers with MusicCast streaming built in. Each speaker has its own amplification, and the left and right speakers connect to each other wirelessly, with a 3 m network cable supplied if you prefer a wired left/right link.

The primary speaker handles the connections: HDMI eARC/ARC for a TV, optical and 3.5 mm analogue inputs, USB, Ethernet and Wi-Fi, plus a subwoofer output. Yamaha builds in its Harmonious Diaphragm drivers, Synergistic Drive amplifier design and YPAO room calibration. The dedicated SPS-70A stands are available separately.

Drivers and Amplification

2-way bass reflex design with a 13 cm (5-1/4") woofer and 3 cm (1-1/4") dome tweeter in each speaker
Harmonious Diaphragm in both drivers, made from a blend of ZYLON (PBO fibre) and spruce, the timber Yamaha uses in grand piano soundboards
Synergistic Drive: a unified circuit design in which the speaker unit connects directly to the amplifier circuit so current flow can be managed
Yamaha rates output at 100 W for the woofer and 60 W for the tweeter in each speaker (320 W total, 160 W x 2)
ES9017S DAC operating in current mode, linear phase design and LLC power supply, as listed in Yamaha's user guide
Rounded cabinet without parallel surfaces, with a 5 mm aluminium top plate screwed into the enclosure

YPAO room calibration with Reflected Sound Control (R.S.C.), parametric EQ and YPAO Volume, using the supplied 6 m microphone
