Mojo, your setup with the M5's are exactly what I need to do I will have the M100 against the side walls but about 3inches from the front wall unfortunately that's what I need to do or else I won't have a living space lol, if I need to I could always plug the rear ports and leave the front open as nothing will be blocking for up to 3.5ft away. I just worry that I am going to have an awesome speaker but can't use it to it's full potential forgive if I am wrong though
