A:AnswerNo, they don't have any mounting hardware in the box, and there's nothing out there that I'm aware of that would let you do that. I would not recommend that, as it would block the up firing Atmos drivers, and render the speaker useless. Well, not useless, but you wouldn't be getting good Atmos, which is why you pay the premium for this bar.
A:AnswerYou can connect Sonos brand in ceiling speakers to arc, but as of right now theres no support for atmos capability. You can use them as rears however. Im not sure of any other ceiling speakers that can be used with arc, so if you want ceiling atmos NOW you would have to get a new wired system. Albeit, they may add it (Sonos ceiling speaker atmos capability) in the future wjth updates, but nothing is confirmed atm.
A:AnswerI have had both and it is a huge upgrade. If you can swing the extra cash for a Sonos sub you will get enough base to anger your neighbors. I added two and it shakes my house.
A:AnswerI do not believe you can. Sonos seems to be a “sonos only” type of company. Im not knocking them, but its obviously for money reasons.
Besides, two Sonos Ones as rears will be years better than homepods.
A:AnswerI have the same tv and use a 4k firestick with no problems. Recently I started using the apps (Netflix, Prime, Hulu) from the LG TV instead of the firestick most of the time, Sound is great either way. You can use the sound bar alone or with the other sonos speakers. The app allows you to seamlessly play any combination of the Arc and any other Sonos speakers. Takes a couple seconds to change. As long as the TV is off you can direct your music to the Arc with the app.
A:AnswerThe beam needs an hdmi arc or optical connection so you'd need a very long wire. I supposed with the right hardware it could be done you'd need to set the beam as a separate room/system and then play to both systems.
A:AnswerHi, and thank you for your question. The Arc is not designed for outdoor use. If you're putting it in a covered patio or something like that, it should be fine. Just keep in mind it's not designed for harsh weather condition. Sound experience can very based on this environment.
A:AnswerBelieve it, or not. It sounds good from 15 feet away. You can actually use tru-sound to have the sound better. (The only down side is that you must have an iPhone to use tru-sound.
Hope this helps !
