Expand your Sereonic TV Soundbox BT-100 system with an extra expansion speaker! Each expansion speaker can be paired with your Sereonic TV Soundbox BT-100 Base System (purchased separately) to provide TV audio wirelessly throughout your home. Up to 50 expansion speakers can be used & paired with each base transmitter.

NOTE: This expansion speaker is only compatible with the Sereonic TV Soundbox Model BT-100. Not sure which model you have? Check the back of your base transmitter/charger. If it has a Bluetooth button, you have the BT-100 and this is the correct expansion speaker. If it does not have a Bluetooth button, you have the BT-200 which is only compatible with the BT-200RX.
