barmanone,
The speakers are small, and this is done to compliment the thin bezel and slim design, so volume will be limited. However, the echo shouldn't be occuring. You might consider going into a retail store to see if the floor model sounds comparable to yours. If the one in the store sounds better, you might have your unit serviced or exchanged.
Keep me posted.
