The answer depends on the speakers you have and the TV you are trying to connect to.

R J Alt,

You will 'likely' need one of these Sonos Home Theatre devices (in no particular order):

• Sonos Playbar 
• Sonos Playbase
• Sonos Beam
• Sonos Amp (not the older Connect:Amp)

As Danny says, it does however depend on the make/model of your TV and the type of speakers you have.

To read more details about the Sonos devices mentioned above (and other Sonos products), please see this LINK.

I have an LG Smart TV, and Sons One speakers

Read the above: that won’t connect. 

I have an LG TV too and the Sonos Beam with two Sonos Ones as surrounds and that works really well.
