Ceiling Speaker Distance from Coffered Ceiling

Hello,

I’m in the process of getting a new construction home built. I’m wondering if there would be any issues putting Sonos ceiling speakers ~18 inches away from a coffered ceiling similar to the coffered ceiling on the perimeter of the living room below image below? Does that give enough distance to avoid any issues?

For context, my home layout is very similar to this open concept with the living room and kitchen / dining being an open space like the image below.

Thank you!
