Planned system: TV = Samsung 78" Amp = Denon X3500H or X4500H Speakers = Klipsch RP-600M Sub = 1x SVS PC13 Ultra Center = Klipsch RP-504C Surround = Mission M7DS Bipolar Atmos Height 1 = 2x Klipsch in-ceiling CDT-3650-C II Atmos Height 2 = 2x Klipsch in-ceiling CDT-3650-C II Note1: This will be done in our Bedroom. Room size is around 15sqm. Ceiling height is around 9 feet. There is a bay window in front where the TV and speakers sit. There is a big window on the right side as well. Note2: No space for another subwoofer unless I give up my SVS PC13 Ultra and get 2x small SVS SB12 (sealed) Note3: This will be used for 100% movies/video via Netflix. No blueray player and no music listening and the like. Question: 1) With my room setup, will I see a significant benefit in going 5.1.4 or should 5.1.2 be good enough? (note: additional $1000+ to go 5.1.4) 2) In "A" (see picture), will it be a problem if my Atmos rear speakers are just on top of the MLP and not in the rear? 3) In "B" (see picture), what would be the best surround for me, monopole or bipole? (should i get a new surround or is my current mission M7ds good enough? I read somewhere that Atmos doesn't work well with bipolar/dipolar speakers that much) 4) In "B" (see picture), should I angle the surround speakers downwards? It is currently around 5 feet above ear level.
