Speaker Placement

I see some room treatments in your future. 

Yes I agree either have to sell them and downsize or do alot of room treatments 

Another option to consider: a Lyngdorf integrated amplifier with RoomPerfect to minimize the bass issues.  The Lyngdorf is supposed to be very effective at this and also sound quite good according to the reviews.  It might be a more elegant and predictable solution than filling your small room with bass traps and other acoustic material.  The main models are the TDAI-2170 and the newer, more powerful TDAI-3400 which has more features and is Roon Ready.   

Personally, I've changed speakers each time I moved to a "new" house in order get the best sound from the room.  Small British monitor speakers were perfect for a condo but got lost in a large family room.   

Not only is the room too small but you have two similar dimensions which will plague the bass. You would do well to use another room if you can.
Putting your listening position against a wall is criminal! So you would be stuck using the 8 foot wall for the system. Assuming two feet from the 8 foot (front) wall and one foot in from the sides this would place the listening position 8 feet from the front wall a safe 4 feet from the rear wall.  

Along the same lines as Kendrick2's suggestion I would find a dealer who will let you borrow an Anthem A/V Receiver which has strong room correction software.  This will tell you if you can tame the bass issues you will have. I had a 12 x 12 x 8 A/V room in my last house that sounded like a disco from the 2nd floor after I installed Golden Ear speakers.  They problem was nicely solved once I installed the Anthem.
