Solved! I have Acoustimass 10 series 4 if we connect to 4K tv it will work good

Solution
ANY speaker will improve ANY TV built-in sound.

The original Acoustimass 10 are designed to work with an AVR (Audio Video, Multi-Channel Surround Receiver) I assume u have one of those? must be between speakers and your TV.

There is no such thing as "4K Sound."
