How to achieve ATMOS with a terrible roof line

Recommended Posts

Imagine this

From the main seating area ( only 3 chairs wide ) I look up and I have a raked ceiling on the left that goes from 2.1 mtrs to 2.7 mtrs.

The rake from the side left wall meets the upper level of ceiling inside where the left ATMOS speakers would go ideally. If I placed the left upper speakers as close to the rake as possible while still being horizontal, that would leave me with a spacing of only 2 mtrs to the right speaker, to be in alignment. This is far from ideal but what to do?

All I could imagine is speakers inside the rake but angled down to vertical, then the other side I would have to suspend the right side speakers like a hanging light fixture would be hung.

 

I have a really lovely room almost perfect for cinema but looks like the ATMOS will be a real challenge

Do you mean 2m between inceiling speakers? If so then it's fine. Most surround effects go to 5 speakers. Those Atmos are for the immersive object base 3D effects.

If you've got an AVR with decent room equalisation it should deal with time alignment issues from the difference in distances.

 

You can also buy in-ceiling speakers with angled drivers - some fixed (e.g. Krix)and others with adjustable tweeter angles.

Yes I do, but it was probably overstated too, it might be 1.8 m . It would look silly in my opinion that the speakers are inside the width of the seating.

If the left speakers were in the rake so that they were 3 or 400mm lower than the right side, it would be ok? You may be right but it would be ugly

The aesthetics may not be to your taste, but it can work well subject to decent room equalisation.

 

What AVR are you planning to use?

 

Also note that the Krix speakers I linked to also come in a standard version for a flat ceiling. I'm using these in my Atmos set-up.

1.8m is still ok methink. + You can paint the grills so they blend in. (thin paint, preferably spray)

From memory I think these are meant to be the same size as a halogen downlight, could be wrong though.

 

Maybe you could get a hanging light fixture to match??

For sound affects you may be ok, that’s what subs are for in surround sound anyway, Bose have made a half decent living using speakers with less oomph than those ones.

 

thinking also a nice white bookshelf speaker like a q acoustics may look ok hanging from a ceiling?? They have Rounded cabinets.

Never seen these before, a cool concept.

Now if they were wireless and battery powered... ....

Personally, I mounted Kef Q100s on angled brackets on my ceiling, aimed at listener position. Never regretted it.

 

Addicted to audio has them ultra cheap too. If they have any left.

 

I'm personally not a fan of in ceiling speakers. After an entire lifetime of hearing and beliieving how emportant enclosure design is to speaker sound, the idea if just cutting a hole in plaster and either leaving an open cavity behind, or doing a half baked enclosure, just didn't make sense.
