Living room in wall 20'x18'

[cterrell16]

I have a new home that I want to add surround sound to. It's my living room which is 20' by 18' but I have open areas around it so it actually much larger. The ceilings are 10 ft but that living room is 14 foot high. I will have to use in wall speakers. The center channel will be under the tv but the left and right channel will be high on the wall so I need the ability to aim them down to my listening and viewing area. I already have a SR7015 receiver. What would you all recommend speaker wise. This is for watching movies, tv and music. I prefer clear and crisp sounds if that makes since. I would like above average speakers but I don't like wasting money just for the heck of it. I'll get a sub and the other channels later. I had jbl pro speakers in my previous home so I want to do better this time. I really don't have a location to listen to different options. Every salesman I have spoken to has given me different options.
