Contemplating moving to Atmos in home cinema (different speakers/amp to Naim setup) and going for in-ceiling speakers (vaulted ceiling across room so can angle them correctly (as long as amp can correct for different distances as will be unusually far away). A setup with angles compatible with Dolby guidelines for 5.1.4 is easily doable. A second sub may also be added later. Amp will probably be the Denon AVC-X6500H or the AVR-3600H.
So the q is, what sort of in-ceiling speakers? Don’t want to spend a fortune, and so if £100 ones will do the Atmos effects fine then I don’t need to spend much more as I don’t want to play music through them… but no reviews out there that I can find which talk about them for home theatre duties, hence my q here - anyone got experiences/advice?
