Speaker placement 5.1

I wasn't quite sure where to place this. I am looking for some help and suggestions on how to setup a 5.1 surround sound in my akward shaped bonus room. I am fully aware in-wall speakers are not the speaker of choice but thats what i have to work with at this point. My bonus room has a dormer on the left hand side and opens up to the staircase on the right hand side. The tv will be lowered about six inches and moved over(centered on the wall) so I can do in-walls for LCR speakers. I'm having a problem on what to do with surround speakers for the rear.






Option 1: I could do one in-wall speaker on the left wall at 90 degrees but there is no place to put the other In-wall surround at 90 degrees on the right side unless i put it across the room. (Would aud. multi-eq correct this type of setup)?

Option 2: Do I attempt to use in ceiling speakers with a pivoting tweeter? I could do 1 in ceiling speaker on the angled wall on the left and then do the other on the ceiling on the right side of the couch.

Option 3: I could just do in-walls on the rear walls placed up high and angle the tweeters in and hope for the best?

Any help would be greatly appreciated.

Thanks

Those woulf work perfectly but unfortunately wayyyyy over my budget

Well starting off looked at htd and monoprice and lately just listened to deaf tech, klipsch and speakercraft. As of now mainly concerned with speaker placement on the rear walls which may influence my decision on which I go with.

Thanks for all the suggestions so far!

Thanks you for everyones replies so far. I do have a ? Just for my personal knowledge. Why wouldn't it be sufficient to in ceiling speakers(one on the 45 degree angle wall and one on the ceiling on the right of the couch) with pivoting tweeters if audyssey would correct the timing? I guess since its not the perfect room its going to be compromises anyway I choose?

Thanks!
