Speakers improve vastly in time.
So many folk buy tvs unaware of that fact.
Check it out online or ask someone in the know.
My Panny P42x60 had speakers tinny and awful I gave them 1/10!
I bought a set of t10s and played them with my Panny speakers.
To my delight the Panny speakers are great and im give them at least 8/10!
So do use the speakers that come with your telly.
