I doubt very many people can achieve the ideal installation as laid out by dolby. All you can do is work within the confines of your space and I am sure that you will still be more than happy with the results. Once all the speakers are in run the atmos setup aand it will take care of the discrepancies. After that you can fine tune if you feel one speaker is overpowering are too distracting.

What others think of me is none of my business.
