Surround Sound Systems
A passive surround system is more flexible because you can assemble the individual components. You can also replace defective parts more quickly than with an active system, which you can see as an advantage.
For even more encompassing sound, go with the 7.1 system. Since the seven speakers are arranged in a circle around you as an audience member, you'll get sound from all sides, even from behind.
To enjoy the full sound experience, you should arrange the individual speakers of the system around your sofa.
Then, in the settings of your TV, you have to set the sound to be transmitted via HDMI, and then nothing can stand in the way of your surround sound. Some systems are wireless versions where you connect the individual modules via Bluetooth or WLAN, among other things.
