Need a TV speaker advice please? Built in Going bad
have a Samsung UN55C7000

Wanted to wait until the Xmas deals to upgrade since about 10 years old.
Still looks and works great but sounds like the speaker is going bad especially with the base,

Do they make a external speaker or sound bar and would that turn off the built in speaker?

Thanks for any advice.

Hate to get rid of it just for the speaker.
When I upgrade I may keep this for a bedroom.

Do have a seperate surround sound system. But my wife does not like it for everyday use. We just use for a DVD movie.
