Hello, M7DS presently reside at side of listening posistin. However, moving them into new cinema room shortly. I was wondering, are they best placed to my sides or can I put them on the rear wall, above my head, firing back towards the front soundstage. I know that they disperse the sound rather than point it, but as my sofa a flush with the wall that I may put them on I wonder if the sound will travel over my head and may casue me to loose rear soundstage. Presently the odd rear effect is clearly going to my side, rather than over my head if that makes sense. I may play around with position before hand but struggling for exceptionally tall friends who can stand with speakers in hands for hours,and I hope to hide any rear speaker wire in new coving before finalising placement. Any advice readily accepted. Thanks, Captain Benefit.
