Versatile wireless features from a super-compact speaker

Looking for a great-sounding speaker for your nightstand or bookshelf? The compact Yamaha MusicCast 20 gives you lots of ways to listen. You can stream from your smartphone via Bluetooth — or Apple AirPlay if you have an iPhone® or iPad®. And the MusicCast 20 can connect to your home Wi-Fi network to give you access to internet radio, podcasts, and more.

Clear sound and intuitive controls

The MusicCast 20 features a 1-1/8" soft dome tweeter for clear highs and a 3-1/2" woofer to fill out the midrange and lower frequencies. Two side-firing passive radiators reinforce the bass. Top-panel buttons include three one-touch presets and an alarm control.

MusicCast: simple multi-room audio

You can combine up to 10 MusicCast speakers and components in a whole-house system, and control them all with Yamaha's excellent MusicCast mobile app. Play your digital music library, internet radio stations, and popular streaming services. There's support for Pandora® and SiriusXM. If you're a Spotify® Premium subscriber, Spotify Connect lets you access all your favorite albums and playlists. You can even stream high-resolution audio files.

Wireless surround sound? Yes, please.

Here's a cool feature for folks who like to declutter. You can use two of these speakers as wireless rear surrounds with any newer MusicCast-capable Yamaha home theater receivers, such as the RX-V485 and AVENTAGE RX-A780.

Bluetooth multi-room streaming

Bluetooth streaming from your phone is handy. But with MusicCast, Bluetooth becomes even more convenient. Stream from your smartphone to the MusicCast 20. Then you can use the MusicCast app to send that audio content to any and all other MusicCast speakers and components throughout your home. It's an easy way to share the audio from any app on your phone or tablet, including podcasts and YouTube™ clips.

A good speaker with decent sound that doesn't take up a lot of space. This is my first wireless speaker and it works well with my wired speakers. No delay either.

Crutchfield customer from Little Rock, AR on 1/23/2019

Crutchfield Customer Review (What's this?)

Good,but not great sound for the price. Wireless feature is terrific, as the speaker can be picked up and moved to wherever there is a power outlet in the home. Paired with the Yamaha N-303 wireless receiver I purchased, and the mobile software app MusicCast on my smart phone, I have convenient music or other audio literally at my fingertips wherever I am in my home.

Good Sound, but Music Cast has Glitches

Carlos from Fort Worth, TX on 1/11/2019

Crutchfield Customer Review (What's this?)

Good sound for wireless speaker of it's size. But no replacement for a quality wired speaker. MusicCast when it works is great. But connection issues are a pain at times. Maybe a range issue sometimes. But problems persist at close range. Hopefully software updates improve situation.

Pros: Sound quality, simple setup, clean ascetic design.

Cons: Music Cast software glitches and reception range.

Deep bass and has a great sound. It can really crank the tunes. It is easy to set up downloading the music cast app. I set my up with SirusXM radio and can't be happier. You can control everything from your phone or you can get an Alexa device to control it.

Crutchfield customer from Lahaina, HI on 11/12/2018

Crutchfield Customer Review (What's this?)

These small speakers have very good sound quality. I am using them in an outside room (covered deck) approx. 20' x 20' Plenty of sound with the two I purchased. I use them with a Yamaha sound bar and the music cast app., not crazy about the app as it is not really intuitive and takes time to figure it out!!! The other components from Yamaha are awesome however and Crutchfield has provided Sterling service and along the way!


Cons: Music Cast

The Mounting bracket is on the back only ( center) [ All About Furniture  Dec 26, 2018 ]
I do not know the speaker is in a different location from where I am now. You might consider contacting Yamaha support. I found them very helpful. [ LARRY  Dec 26, 2018 ]
I just checked it for you & I only saw the one on the back, which is very obvious. Sorry! [ SUSAN  Dec 26, 2018 ]
There is one mounting thread. It is on the back of the speaker. [ John  Dec 26, 2018 ]
the mounting thread is only on the back. My speaker is attached to a simple mount I picked up on Amazon for $15/pair which is anchored to a wall stud, and it's works great. [ Spencer  Dec 26, 2018 ]
Mounting thread is on the back only. I have it on Mounting Dream floor stand. It works very well. Most mounting systems come with multiple bracket arrangements. [ David  Dec 26, 2018 ]
Only back of the speaker. [ Andrzej  Dec 26, 2018 ]
I called Yamaha tech support. They were very helpful . The negative is the long wait time before someone answered the phone. [ LARRY  Nov 03, 2018 ]
If the receiver has MusicCast it will work but tough to set up. The app is quite clumsy. Speakers sound good tho [ John  Nov 02, 2018 ]
