Connection
The pairing speaker should be installed at least 5 feet apart but at
most 15 feet from the main speaker (with the included speaker wire).
If the pairing is installed further apart, you need to purchase an
additional speaker wire cable, ideally in thicker gauge (14AWG or
higher) for installation longer than 30 feet apart. Pairing speaker
performance may decline over long distance, especially when using
low-quality speaker wire.
