I will assume listening room not HT.

For your room:

Sit 36 3/4” off back wall to seated ear location.

Place speaker 27 1/2” to tweeter off sidewall.

Place speaker 36 3/4” to tweeter off front wall.

Mount tweeter on stand 32” off floor. Or 18-20” stands.

For toe in use a laser. Put masking tape on your seatback and mark 1” increments off centerline of room. Toe in to 13 1/4” off centerline for each speaker. Will differ depending on your treatment locations. Toe out for more space. Toe in for stronger vocals.

Dont need a sub if you do this in that size room. My M5s are set up this way. Cant hear speakers -dissapeared. Can feel in my chest if I want them to. Enjoy!

My room is 11.5 x 18 x 8’ for reference.
