Speaker placement open wall listening room

[Mwilder]

I need some advice with speaker placement. My room is 15 x 12.5 with 9 ft ceiling. The speakers are placed on the 15 ft wall. I cannot get the imaging and the bass both right at the same time. There are 2 ft side walls at the listening area. Behind the listening area is a depth of 10 ft with a 17 ft ceiling. I am using ML Sequels. Any suggestions would be greatly appreciated.
