Difference between TV's own subwoofer and ordinary TV's external speakers

The subwoofer that comes with TV is a built-in device to improve sound quality.

The original intention of the external speaker design is to bring better sound quality performance to the TV set on the premise of saving space as much as possible. More realistically, today's TV sets, as the future display direction, tend to be bigger and thinner, inevitably sacrificing certain sound quality.

Because the sound quality effect is often proportional to the volume of the sound generating unit, that is to say, the listening sense that TV can bring is limited. Its sound quality is actually between traditional home theater and TV.
