Welcome to the forum. Just an FYI you will get alot more attention if you start a new thread rather than in a current thread. As to your inquiry,do you plan to implement ATMOS, though with 7ft ceiling i would think not. Do you have a sub or plan to add a sub , if not then i would say the M100's HP and depending on how much room you have, the VP160 would fill the bill and is very well liked and respected.Are you using a projector or HDTV and how far away do you sit and how many rows of seats. I would say with what you have a 7.1 setup would be your best bet. I also would suggest powering the front 3 with an ADA and let the receiver take care of the rest.
specially when they are placing those M100's about 3" into the room. Chews up real estate fast
