Atmos ceiling speaker placement
I’ve just recently set up my first full Dolby atmos 7.2.4 setup with a Denon 4300H, 3 pairs of KEF Q100’s & Q200, and 2 cheap pairs of Pyle in ceiling speakers. The affect is certainly noticeable, though a bit on the subtle side. Initially, I wanted to spread my ceiling speakers out to give my setup a “wider soundstage” for the atmos affect, but now I’m wondering if I’d be better off moving them in closer.
Right now I have the speakers placed at a 35 degree angle from horizontal, but I’m wondering if placing them at a 45 degree angle would actually enhance the height affect for all seating positions, and if by “expanding the sound stage” what I’ve really done is muted the height effect. Speakers are installed in a 7’-5” drop ceiling. MLP is 3’ off the ground on a large U-shaped sectional couch. Speakers are placed 6.5’ forward and back from MLP, so all seating positions are between front and rear ceiling speakers. Vast majority of the time, MLP willl be the only seats used.
Has anyone experimented with ceiling speaker placement? Is 45 degrees considerably more effective than 35 degrees for spatial audio, even though 35 is still technically in the recommended range? I know speaker dispersion that far off angle isn’t great, which is probably why Audessey saw fit to boost the speakers by 12dB.
