Thank you to all who reply, I appreciate your help.
Currently I have an Arc with a Sub 3 and a pair of Moves. They are two separate rooms. I have just now ordered a pair of Fives and a second Sub3.

This I believe will allow me to have a surround system. Is there a best way forward to achieve this? Thank you for any and all suggestions. I
