It ultimately depends on your specific needs and preferences. A soundbar with surround sound typically offers a more immersive audio experience, with separate speakers to create a more realistic surround sound effect. On the other hand, an adaptive soundbar is designed to analyze the acoustics of your room and adjust the sound output accordingly, providing a more customized listening experience. If you prioritize a more immersive surround sound experience, a soundbar with surround sound may be better for you. However, if you value a more personalized and adaptable audio experience, an adaptive soundbar may be the better choice. **

A power output of 30 watts can be considered good for a Bluetooth speaker, especially for smaller to medium-sized rooms. It can provide sufficient volume and clarity for casual listening and small gatherings. However, for larger rooms or outdoor settings, a higher power output may be more suitable to ensure adequate sound coverage and quality. Ultimately, the suitability of a 30-watt power output depends on the specific needs and preferences of the user. **

To expand a soundbar to have surround sound, you can add additional speakers to create a multi-channel audio setup. One option is to purchase a separate set of surround sound speakers and connect them to your soundbar using speaker wire or a wireless connection, if supported. Another option is to invest in a soundbar system that includes wireless surround speakers, which can be placed behind or to the sides of the listening area to create a more immersive surround sound experience. Some soundbars also support the addition of a subwoofer for enhanced bass, further enhancing the overall audio experience. **

There could be several reasons why the rear speaker is not working in surround sound. It could be due to a loose connection or faulty wiring between the speaker and the audio receiver. Another possibility is that the speaker itself is damaged or not properly set up in the audio system settings. It is also important to check if the audio source being played is encoded in surround sound and that the receiver is configured to output sound to all speakers. **

No, you cannot directly connect a Bluetooth speaker to an active subwoofer. Bluetooth speakers are designed to receive audio signals wirelessly from devices like smartphones or computers, while active subwoofers typically require a wired connection to a sound system or amplifier. You would need to connect your Bluetooth speaker to a device that has audio output capabilities, and then connect that device to the active subwoofer using the appropriate cables. **

To use surround sound with a Bluetooth jack, you will need a Bluetooth transmitter that supports surround sound audio formats such as Dolby Digital or DTS. Connect the Bluetooth transmitter to the audio output of your device using a standard audio cable. Pair the transmitter with your Bluetooth-enabled surround sound system and make sure it is set to receive the audio signal. Once connected, you should be able to enjoy surround sound audio wirelessly from your device through the Bluetooth jack. **

Ultimately, the better speaker would depend on individual preferences and the specific sound qualities desired. **
