Soundbar or surround speakers for open floor

Our living area has tiled flooring- open floor plan- 20 ft ceiling.
55" TV.

I like the simplicity of a soundbar with a wireless subwoofer as opposed to 5-6-7 speakers with receiver and subwoofer.

Right now we are testing out Energy speakers 5.1 with subwoofer and Pioneer reciever :VSX-1022-K
Because our room is open the sound is 'thin' when we watch TV. and this is becoming very frustrating.

(When watching The Dark Knight, sound was great.)

we watch mostly cable TV . we watch movies on BluRay maybe twice a week.

Which soundbar would be good for us- in your opinion?

Thanks for your reply-

Well in the meantime my husband wanted to keep the Energy speakers as I stated above and get everything tuned up/adjusted
which we did, and the sounds is great!

We didn't need to call in anyone to adjust the speakers to our room...the receiver did all that for us. It's a world of difference! I can't believe it...even with our tile floors,
high ceiling and no walled in room.
