Product Description


Multi-room, MusicCast

The Yamaha MusicCast 20 is part of Yamaha's hugely impressive network audio system, MusicCast. With MusicCast you can control all your compatible Yamaha MusicCast products via your smartphone or tablet. Play the same music on all the components or split the sound into different zones for different moods in each room; the choice is yours. The MusicCast CONTROLLER app also lets you operate the speaker and change settings quickly and easily.


Voice control via Alexa*

With Amazon’s hugely popular Alexa voice control integration, all you have to do is ask. “Alexa, ask MusicCast to play Favourite 1 in the kitchen”, is all you need to say to get the music started. *Amazon Echo or similar required for voice control. 


Music streaming services. Sorted

Getting the MusicCast 20 (also known as Yamaha WX-021) to play your music is easy. Compatible with Spotify, Tidal, Deezer, Qobuz, Pandora and Napster, all of the major providers are covered. Simply sync with your smartphone or tablet and you’re good to go.


Advanced networking including Apple AirPlay and Bluetooth

Built-in Apple AirPlay means that you can stream music from your Apple iPod Touch, iPhone, iPad or other compatible Apple device, wirelessly. If you use another brand of smartphone or tablet then you've also got Bluetooth, for easy music streaming from your portable device.


Find your favourites, with three presets

Finding your favourite Internet radio stations can be a chore, which is why the MusicCast 20 has three, soft touch, presets at the top of the device. Store and recall at the touch of a button.


Pair up for stereo sound

Use the MusicCast app and you can pair up two MusicCast 20 speakers for stereo sound. Perfect in larger rooms or wherever you prefer a more immersive, stereo sound, this function doubles the ability of this already impressive speaker.


Use as wireless rear speakers

Another great feature with these flexible speakers is the ability to use them as wireless rear speakers. Simply pair with a compatible Yamaha MusicCast AV receiver, connect to the mains supply and cut out the speaker cable to the rear speakers – perfect for when you’ve hard floor coverings that accept cable underneath.


Powerful sound

A two-way speaker system gives a crisp, clear sound, throughout the frequency range. With twin ABRs (Auxiliary Bass Radiator) either side of the unit the bass is also powerful enough to easily fill most rooms.


Compact design that can be wall mounted

With its compact dimensions and unobtrusive design, the MusicCast 20 goes just where you want it. Use it on a desk, bedside table or kitchen worktop - the MusicCast 20 fits in almost anywhere. For even greater versatility, the speaker can be wall mounted via a simple keyhole slot fitting.


Take your MusicCast system to the next level, with the powerful Yamaha MusicCast Sub 100.

Made for MusicCast
Featuring built-in wi-fi connectivity with MusicCast compatibility, the Sub 100 makes the ideal addition to your Yamaha MusicCast system. Link up with a compatible Yamaha device and enjoy wireless control. The subwoofer works in single, stereo and surround sound MusicCast modes, making it fully upgradable with your MusicCast Hi-Fi or AV system. An Ethernet connection is also standard for a wired network connection.


Natural sound through Twisted Flare Port

The Yamaha MusicCast Sub 100 (also known as the Yamaha NS-NSW100) uses a revolutionary new design of bass port for a more natural, less distorted sound. Rather than using straight sides, this Yamaha's port is twisted and flared to smooth and diffuse the air output. This reduces distortion, giving you a tighter, cleaner bass response that's much truer to life.


Bass to make the room shake

Driving the dedicated eight-inch sub is a powerful amp with 130 watts output power. This not only produces a deep, powerful bass but also gives precise control of the bass - meaning it doesn't distract from the rest of the music or soundtrack.


Incorporating Yamaha's renowned YST for bass depth

Providing Yamaha speaker systems with awesome bass for decades now, YST (Yamaha Active Servo Technology) optimises the output to give not only a powerful bass response but also one that's stable and accurate. In short, its powerful bass without the flab.


Made to match you MusicCast

Finished in piano black or white, this glossy subwoofer is much more attractive than most subs. It’s also designed to match other MusicCast devices, giving a clean and cohesive style from your complete music system. For ease of use, the master volume control and status LEDs are at the top, instead of the rear of the unit.
