Hello all, thank you for your time. I really need help from some serious home theatre audiophiles, with my atmos configuration. I have read many forums and many people’s 2 cents, and I’m still stumped. I am hoping to do 5.2.4. My home theatre space is 21 feet long by 13 feet wide, with a ceiling that is only 6 feet 11 inches high. Since I have a pool table also in that space, my mlp is 17.5 ft away from the front speakers, and right up against the back wall. I may consider moving my couch a hair away from the wall if absolutely necessary. I have discovered 5 possible scenarios. #1. In ceiling speakers. #2. Exposed speakers mounted “on” the ceiling (if you don’t want to cut holes). #3. Height elevation speakers set as the atmos channels. #4. Atmos up-firing modules. #5. Towers with built in atmos modules. From reading, here are what I have deduced are the pros and cons to each setup. #1. In ceiling speakers are supposed to be the best if your ceiling is high enough however, I have heard they sound too directional if you have a low ceiling, and my ceiling is only 6 ft 11 inches high. Also, my couch is right against the wall. This also seems to rule out in ceiling speakers since I can’t put 2 behind me. Plus, I don’t want to cut holes. #2. Exposed ceiling speakers makes it so I don’t have to cut holes (and you can get thin wall speakers to use) however, I have the same problem as in ceiling speakers with my ceiling being too low and couch right against the wall. #3. As for height elevation speakers, someone did a test with sound meters and said that speakers in the height position set as atmos channels, most closely represent ceiling speakers. However, their set up was not as far away as mine, and with my mlp 17.5 ft away from the front wall, I am skeptical that the height modules will project the sound that far. If I am mistaken about that please correct me. #4. Up-firing atmos modules mounted on towers apparently are better for lower ceilings but, sound very localized. I have read the modules made by Atlantic Speakers help a bit since you can tilt the tweeter however, apparently even they sound fairly localized. Also, I have heard up-firing atmos modules sound like a mess when up-mixing music. #5. Towers with built in atmos modules apparently help make the sound less localized but, even they have their issues. They still will make up-mixing audio sound messy. Also, apparently it’s tough to position the towers to both sound great as main speakers, and as atmos modules. Also, as far as I know the only speakers with built in atmos modules are the pioneer elite and the klipsch, with the klipsh sounding better. However, with the klipsch, you have to put up with the treble fatigue of horn tweeters. Also, I would have to scrap all of my speakers I have spent decent money on, for new speakers. With all being said, would you go with option #1/#2, In/on ceiling speakers? or... #3. Height elevation speakers (ex: svs prime elevation) set as atmos speakers? or... #4. Atlantic Speakers atmos modules? or... #5. Towers with built in atmos modules? Fyi my receiver is a marantz SR7013 and my speakers are definitive technology BP10s for the fronts, and definitive technology centre and surrounds (tv is an 86 inch lg but that's irrelevant). I realize def tech speakers don’t get a lot of love but, I am not here to argue that point right now. I am just here get some help with my atmos set up. Thanks in advance to all who reply.
