Wireless Wi-Fi and Bluetooth® connections. Output power: 40W RMS (Two 10W drivers + Two 10W subwoofers). Certified for use with Amazon Alexa (including Amazon Music, Spotify, Tidal and iHeartRadio).
Love the Alexa and love the look. Sound is OK but the real disappointment was the advertisment of connecting more bluetooth speakrs but that only seems to work with their brand of speakers. Too bad it wasn't mentioned anywhere. I would pay $ 65 for it.
