I'd push them up. Make sure all the joints are well sealed. Wrapping with self adhesive damped mass like Kilmat or DynaMat will provide some benefit in keeping them from picking up sound and transmitting upstairs.
Pushing air duct up for in-ceiling Atmos speakers
I'm finalizing the placement of my 7.2.4 speaker layout in my basement, and of course the exact Atmos 45 degree placement that lines up with my front speakers falls right on the joist cavity that contains 6" hvac ducts..
The speakers will in-wall Triad bronze speakers that 4" tall, and I can push up the ducts so that the bottom of the speakers will line up with the double 5/8 drywall that will be on the ceiling. My question is, that will cause my ducts to have a slight arc from one end to the vents. I understand that this isn't the best solution, but it's either this or move the ceiling speakers where the lights are, and I'd rather not bring them in that far from the room sides. I'll be packing the cavity with insulation, and can put some between the speaker and duct, but I'm more concerned with the duct performance when it's not as level when I push it up. Does anyone know if that would cause an issue with the hvac air flow/pressure?

All good! I love getting advice on my project. Most of my basement is already build like this, so we'll see what happens
I did have a question to your other post tho:
You would put the speakers on the inside joist cavity of the lights? That would put them 4 feet apart, and 6 feet from each side. That puts them very centered. If what you say is true, I think I'd rather just put the speakers exactly where the lights are and move the lights around a bit to accommodate, as I'd be a little hesitant to bring them so centered. I have a 140" wide screen and my L/R are going to be about 3-4 feet from the walls on each side.
That is what I was suggesting, and I do believe you would be very happy with the result. There is a reason so many people decide to angle-in their Atmos speakers. The only reason I would back away from that suggestion is if your primary listening position would put you directly in line with one side or the other (or outside of them). But the lightcan joist space is perfectly good.All good! I love getting advice on my project. Most of my basement is already build like this, so we'll see what happens
