A:Answer Hello!
The Free Space 51 Speakers are passive speakers, and as such are required to be connected to an amplifier to play. These are connected through the Bare Wire Red(+) and Black(-) Wires.
Based on your interest with Wi-Fi/Bluetooth, we would recommend our SoundTouch SA-5 Amplifier, which can connect to your Wi-Fi network through our SoundTouch app, or through Bluetooth directly.
We hope this helps you make a decision you're happy with!
