I am shifting to a new room and I am planning to buy z-5500 speakers.. I want to know if my room size is suitable for optimal surround sound effect…

My room dimensions are as below.. “mon” represents where the monitor would be placed.. The opening on the left is open right now.. I am planning to fit a big plywood door there.. is this room suitable for the speakers and what would be the optimal locations for the speakers To cover the entire room or part of a room?

well i have set it up in small room.
room size is 15x15 and i am not happy with sound. it lacks the punch.
i dont know if there is hardware problem or my HD audio is causing problem.
woofer is placed in corner on the floor. even i have kept all satellites on the floor still i feel audio is not that powerful.

any suggestion?
