Performance that has you covered

Most speakers can’t deliver sound evenly over a large outdoor area. But our outdoor speakers are uniquely engineered to give you full stereo performance across a much wider space. Choose 251 environmental speakers, our best wall-mounted outdoor speakers for powerful full-range sound. Or the versatile 151 SE environmental speakers that you can mount horizontally or vertically.

Built for the great outdoors

Whether you’re unwinding on your own or entertaining friends and family, you want your music to keep up with you. These speakers will stand up to the cold, heat, snow and rain. So when the weather’s just right, your music will be right there with you.

Everything you need to stream music

Both SoundTouch® outdoor speaker systems include the SoundTouch® SA-5 amplifier and SoundTouch® wireless adapter. The SoundTouch® app also transforms your phone into a powerful remote so you can control your music from anywhere in your home.

SoundTouch® SA-5 amplifier

Can I mount the speakers horizontally and vertically?

251 speakers are designed for vertical mounting only. 151 speakers can be mounted horizontally and vertically.

What conditions and temperature extremes can these speakers withstand?

Our outdoor speakers are designed to withstand:
    -  Sun, high humidity (rain and snow), salt and fog
    -  Temperature extremes (-40° F to 158° F; -40° C to 70° C)
    -  Permanent outdoor installation

Where should the SoundTouch™ SA-4 adapter be located when installing the SoundTouch™ SA-4 amplifier?

We recommend placing the SoundTouch™ adapter within one wall of the location where the speakers and SoundTouch™ controller are used. Also, the SoundTouch™ adapter should never be placed in a metal wall panel or cabinet.

Can I control multiple systems with one SoundTouch™ controller?

No. The SoundTouch™ controller is designed to control one SoundTouch™ system at a time.

What is the range of the controller?

Approximately 70 feet from the paired system in wood-construction homes. In concrete, stucco or brick homes, the range will likely be less and may vary. The number of other active wireless devices in the house may affect range as well. You can also use the controller outdoors, but you shouldn’t leave it exposed to the elements or mount it outside of your home.

Can I mount the SoundTouch™ controller to a wall?

Yes, anywhere indoors with the included wall-mount bracket. The SoundTouch™ controller magnetically attaches to the wall mount so you can easily take it when you need it. The magnet is in the wall-mount—not the controller—so for example, you cannot attach the controller to a refrigerator.

What is needed to set up my SoundTouch™ outdoor speaker system?

If you have a computer and a home Wi-Fi network, you have all you need for setup. Everything else required is included with the products that are included in this package.

Do I need a smartphone or tablet to use the system?

No. You can use a computer to explore music and personalize presets using the SoundTouch™ app. And you can access your presets directly through the SoundTouch™ controller, without having to use a tablet, smartphone and, once set up, a computer.

Are SoundTouch™ systems Bluetooth® compatible?

No. SoundTouch™ systems are designed for use in and around the home on your Wi-Fi network. Bluetooth technology is best-suited for mobile on-the-go applications where close-range connections are generally preferred.

What Internet streaming music can I play?

SoundTouch™ systems let you play Internet radio stations from around the world. Where available, you can also play music services like Deezer, Spotify®, iHeartRadio™ and Pandora®.

Can I play music stored on my computer?

Yes. SoundTouch™ systems can play music stored on your computer that is managed by iTunes® or Windows Media Player.

Can I stream different music to different rooms?

Yes, if you have multiple SoundTouch™ products, you can stream different music in different rooms, the same music in every room or customize zones to play what you want where you want.

Can I stream from apps or music stored on my smartphone?

You can stream music from an iPhone®, iPad® or iPod touch® to SoundTouch™ Wi-Fi music systems via AirPlay®. You cannot stream music stored on an Android™ phone or from apps on an Android phone.

How many systems can I have on my network at one time?

It depends on the bandwidth of your home Wi-Fi network. For most homes, we expect you can have up to four systems connected wirelessly. For more than four rooms, we recommend using Ethernet wired connections to some of them.

What operating systems are compatible with the SoundTouch™ app?

The app is compatible with Windows® XP, 7, 8; 64-bit Macs running OSX 10.6.8 and later; any iPhone, iPad or iPod touch running iOS5 and later; Android devices running Android 4.03 and later.

Can I play stored music from an NAS drive on SoundTouch™ systems?

Yes, SoundTouch™ systems are compatible with select NAS drives, including Synology’s DiskStation and Western Digital’s My Cloud™, so you can stream your personal music library even while your computer is off.

What audio formats are supported by SoundTouch™ systems?

Right now, MP3, WMA, M4A, AAC and Apple® Lossless formats are supported. We plan to add FLAC as part of a software update in early 2014.

I already own speakers that I’d like to use to stream music. How can I do this?

You can use your own speakers to easily stream music with the SoundTouch™ SA-4 amplifier. The SA-4 amplifier works with your existing home Wi-Fi® network, so you don’t need any extra equipment.
