The Samsung Soundbar HW-S61D can be connected to the Samsung Freestyle Gen2 projector via Bluetooth, but there are some limitations and potential issues to be aware of:

- It is possible to connect the soundbar to the Freestyle via Bluetooth, but this can lead to delays (lag), which is particularly undesirable when playing Dolby Atmos.
- A stable and lag-free connection can be established via Wi-Fi, which is recommended for better audio quality and Dolby Atmos support.

For an optimal connection and best audio quality, the use of Wi-Fi instead of Bluetooth is recommended.
