Yamaha NX-70A – Wireless Hi-Fi Speaker with Room Calibration and TV Connectivity

The Yamaha NX-70A combines hi-fi sound, music streaming, TV audio, and app control in a modern active speaker system for the living room. The system consists of a PRIMARY and a SECONDARY speaker, which are wirelessly connected by default. This makes the NX-70A particularly suitable for anyone who wants to enjoy high-quality stereo sound without setting up a classic hi-fi system with a separate amplifier.

What makes the Yamaha NX-70A special:

• Wireless L/R connection – left and right speakers connect automatically, eliminating the need for a cable between them.

• Harmonious Diaphragm™ – the uniform diaphragm in all speaker drivers supports a consistent sound image from low to high frequencies.

• Synergistic Drive™ – amplifier and speaker drivers work together as a coordinated system to minimize distortion and make the sound clearer.

• YPAO Room Calibration – automatic measurement adapts playback to the room, placement, and listening position.

• MusicCast and High-Fidelity Streaming – Spotify Connect, Google Cast™, AirPlay, TIDAL Connect, and Roon Ready are integrated.

• HDMI eARC/ARC – TV audio can be easily connected via HDMI and conveniently controlled via the TV remote control.

Hi-Fi for Music and TV Reimagined

The NX-70A is designed for everyday listening: music streaming, TV audio, internet radio, podcasts, Bluetooth, USB music files, and network sources can be played through a compact stereo system. The PRIMARY speaker handles central control, connection to external devices, and synchronization with the SECONDARY speaker.

Consistent Sound from Low to High

All speaker drivers of the NX-70A use Harmonious Diaphragm™. The diaphragm combines the PBO fiber ZYLON™ with spruce wood, which is also used for grand piano soundboards. The goal is a natural and coherent reproduction, where voices and instruments remain consistent across the entire frequency range.

Coordinated Interaction of Amplifier and Speaker

Synergistic Drive™ combines the amplifier circuit and speaker drivers into a coordinated system. The direct connection of the driver to the amplifier circuit allows for more precise control of current flow. This precisely controls the interaction between amplifier and speaker, which is intended to preserve the original character of the playback.

Sound Image for Your Room

YPAO™ measures the acoustic properties of your listening room with the included microphone. YPAO R.S.C. takes into account early reflections that can affect stereo clarity, while a precise equalizer adjusts tonal balance. This is particularly helpful when the speakers are not freely placed in the room but are arranged to suit the living space.

TV Audio via HDMI eARC/ARC

The NX-70A can be connected to a TV with eARC/ARC or ARC via the included HDMI cable. CEC enables simultaneous power on/off and volume control via the TV remote. Important: The TV jack reproduces PCM 2-channel audio; the audio output on the TV must be set accordingly.

Easily Integrate Other Sources

In addition to HDMI, optical digital connection, analog AUX input, USB, Bluetooth, network, and a subwoofer output are available. An active subwoofer with an integrated amplifier can be connected via the SUBWOOFER jack. After connecting or removing a subwoofer, YPAO should be run again.

Streaming Throughout Your Home

MusicCast connects the NX-70A to streaming services, internet radio, podcasts, music on smartphones, PC/NAS, and other MusicCast devices. Audio can also be shared between MusicCast devices in different rooms. For Apple users, AirPlay is available, Google Cast™ enables streaming from compatible apps, and Roon Ready integrates the speaker into an organized Roon music library.

Conveniently via App, Remote Control, and TV Control

In everyday use, you control the NX-70A via the MusicCast Controller app, the included remote control, the information display on the PRIMARY speaker, or via the TV remote control if HDMI-CEC is enabled. Input sources such as TV, OPTICAL, AUX, Bluetooth, NET, and USB can be selected directly. Favorite content such as tracks or internet radio stations can be saved as presets.

Flexible Left and Right Placement

By default, the PRIMARY speaker is set up as the left speaker and the SECONDARY speaker as the right speaker. If necessary, the channels can be swapped if the room or cable situation requires it. For a more stable connection or higher quality transmission between the speakers, the included network cable can be used instead of the wireless L/R connection.

Room Placement

For placement, at least 20 cm of clear space above, to the sides, and behind is provided so that heat dissipation is not hindered. When using wireless functions, metallic walls or tables, microwave ovens, and other wireless network devices should be avoided as much as possible, as such obstacles can impair transmission. We recommend small to medium-sized rooms for placement up to 30 m².

Stable Enclosure with Sound-Oriented Shape

The rounded enclosure shape avoids parallel surfaces and helps suppress internal standing waves. The rigid construction controls unwanted vibrations. A 0.50 cm thick aluminum plate on the top is firmly screwed and reinforces the enclosure into a solid structure.

Pros and Cons

Suitable for

• Music lovers seeking a modern hi-fi stereo system with streaming, app control, and room calibration.

• Living spaces where left and right speakers can be flexibly placed without running a cable between them.

• TV users who want to easily integrate TV audio via HDMI eARC/ARC and control it with the TV remote.

• MusicCast users who want to share music and TV audio with other MusicCast devices in their home.

Less suitable for

• Users expecting a completely wireless power supply, as both speakers each require a power cable.

• TV setups where multi-channel surround sound via HDMI is the focus, as the TV jack reproduces PCM 2-channel audio.

Our Conclusion

We see the Yamaha NX-70A as a very interesting solution for customers who want to combine hi-fi stereo, streaming, and TV audio in a living room-friendly system. The combination of wireless L/R connection, YPAO room calibration, MusicCast, and HDMI eARC/ARC is particularly strong. It's important to note the necessary power supply for both speakers and the PCM 2-channel output on the TV input.
