Hi Fuzzy, We do make a number of passive outdoor speakers. Our 151, 251, and Free Space 51 models are all intended for outdoor installation and use. These speakers would need to connect to an amplifier to power them. If you were to purchase a set of these along with our SA-5 amplifier, you would be able to play your streaming music via the SoundTouch app to these out door speakers with ease. They would even be able to synchronize to play the same music together with the SoundTouch 20 across your Wi-Fi network. Hope this helps!
