Klipsch Heritage The Three Stereo System

Can I hook this up to my LG smart tv?

If your TV has RCA audio out, then yes.

It also has a digital input USB Type B and a 3.5mm input, the latter of which a lot of newer TVs have an output for.

Kind of bitter because I bought this (https://sellout.woot.com/offers/klipsch-heritage-the-three-stereo-system-16) a few days ago thinking it was a good deal since these were $319 before on Woot. But this is the same price, has all the accessories and a longer warranty.

EDIT: I just got an email and $26 refund
