A:Answer Hello, DW.
Thank you for your question! You can connect the Echo Show to the Wave SoundTouch speaker, and ask Alexa to play music. The music will play through the Wave. The initial setup would take place in the Amazon Alexa app.
If you have the Wave SoundTouch Music System IV, this version can connect to the Echo using Bluetooth. For the original Wave SoundTouch, you can connect the Echo with a 3.5 mm audio cable.
Please don't hesitate to reach out to our support team at 1-800-367-4008 for further assistance. They are available M-F 9 AM to 9 PM Eastern. Thank you, and have a great day!
