In my 5.1.2 setup for my atmos setup I have bookshelf speakers mounted on the wall above of (& just a bit behind) my front speakers at the highest point of the front wall just below the ceiling with the speakers pointed at main listening position. i cannot mount them on my ceiling as i have a POP false ceiling which wont take their weight. my avr is set to Front Heights.
was wondering if i would gain anything by buying a pair of in-ceiling speakers and mounting them on the ceiling and setting them as Top Fronts or Top Middle? is there any difference in experience of movies and music (especially when using the dolby/dts upmixers since most of my media is not atmos encoded) in one setup vs the other?
