Hello guys, I'm really new about separate system thus need help about the characteristic of the sound for Mordaunt short and Mission speakers. How the tonality for these two made. Specifically for: Centre: Mordaunt short MS905C vs Mission 77C Front: Mordaunt short MS906 vs Mission M74/774 Actually currently I have MS905C and paired with mission 702e. So want to get M74 and bring the 702e as surround. Is it acceptable match with MS905C or definitely I need 77C? I really appreciate for the help. My AV is Sony STR-DH810 Many thanks.
