How to choose the right one
Check channel configuration
You must decide between a 4.1 and 3.1.1 channel layout. The S40TR uses a 4.1 setup for standard surround sound. The S70TY offers 3.1.1 channels for height effects. Choose the 4.1 model if you want clear left and right rear separation. Pick the 3.1.1 option if you prefer overhead audio cues for movies. This choice defines the basic shape of your sound field.
Verify wireless connectivity
Ensure the rear speakers connect without extra cables. Both listed models use wireless links for the rear units. This removes clutter from your living space. You only need power cords for the main bar and subwoofer. Check that the connection method is wireless before buying. Wired rear speakers require running cables across walls or floors. Wireless setups are cleaner and easier to install for most homes.
Confirm subwoofer inclusion
Look for a wireless subwoofer in the package. Low frequencies need dedicated hardware for full impact. Both the S40TR and S70TY include wireless subwoofers. This ensures you get deep bass without extra purchases. Verify the subwoofer is wireless to match the rear speakers. Some budget models sell subwoofers separately. Inclusion simplifies your setup and ensures balanced audio output from day one.
Match soundbar width
Compare the physical width of the soundbar to your TV. The S40TR is 28.4 inches wide. The S70TY measures 37.4 inches across. A wider bar covers more of your screen visually. It also often provides broader sound dispersion. Measure your TV stand or cabinet space first. Ensure the soundbar fits without overhanging too much. Proper sizing maintains a clean aesthetic in your viewing area.
Prioritize audio formats
Check if the unit supports Dolby Atmos or DTS:X. The S70TY supports Dolby Atmos for object-based audio. It also handles DTS:X for compatible content. The S40TR focuses on standard channel decoding. Choose the S70TY if you watch many 4K movies with height channels. If you mostly listen to music or standard TV, the simpler format may suffice. Format support determines how immersive your audio experience will be.
