How to Choose a Smart TV with Great Built-in Sound?

Selecting a TV with quality built-in audio requires understanding key technologies and your specific needs. Let me share insights from testing dozens of models.

Understanding Audio Technologies

Dolby Atmos creates three-dimensional sound by adding height channels. TVs with this technology produce more immersive audio that seems to surround you.

DTS Virtual:X provides similar spatial audio without requiring additional speakers. This processing technology widens the soundstage beyond the TV’s physical boundaries.

Acoustic Surface Technology, exclusive to Sony, vibrates the screen itself to produce sound. This creates perfect synchronization between image and audio sources.

Room Size Considerations

Small rooms under 200 square feet work well with basic TV speakers. Even budget models can fill these spaces adequately.

Medium rooms between 200-500 square feet benefit from TVs with enhanced audio like Dolby Atmos or DTS Virtual:X. These technologies help sound reach all seating positions.

Large rooms over 500 square feet need powerful built-in systems or will require external audio. Look for TVs with at least 40 watts output and object tracking technology.

Speaker Configuration and Placement

Down-firing speakers bounce sound off furniture, potentially muffling audio. Front-firing or side-firing configurations provide clearer, more direct sound.

TVs with multiple speaker positions (like Sony’s Acoustic Multi-Audio) create better sound distribution. The audio seems to come from the appropriate screen location.

Consider your mounting plans – wall-mounted TVs may have different acoustic properties than stand-mounted ones. Some models include wall-mount audio optimization.

Optimizing Your TV’s Built-in Audio

Start by running any auto-calibration features your TV offers. Many models can analyze room acoustics and adjust accordingly.

Position your TV at ear level when seated for optimal audio projection. This alignment ensures dialogue clarity and proper soundstage presentation.

Experiment with audio presets for different content types. Most TVs offer modes for movies, music, sports, and news that genuinely improve the listening experience.
