Thanks for your reply Dean. When listening to music I have sensed that I was lacking some mid bass possibly around 100Hz. My measurements confirmed this. I have just changed the receiver settings for the front speakers changing the setting from full range to 80hz and performed the test again. I have a dramatic improvement now.
Do my results below appear to be acceptable:
