Have you considered a 'Sound Base'?. It's like a sound bar but you sit your TV on top of the Sound Base. The speakers are built in to the unit and seem to be better quality than the hit and miss sound bars.
The price is normally that bit dearer but worth it for that Home Cinema Sound without the trailing cables to each individual speaker.
They can be very loud and bassy, so you must consider your neighbours regarding the noise.
I can vouch for the 'Canton DM 50'. Brings your TV sound to life.
Always try a demo in store to see if it meets your expectations before buying.
