The room I'm using in the basement has an existing drop ceiling, that I don't want to replace at this time. Looking at getting some speakers for Dolby Atmos and considering the M3 in-ceilings, but the only way I can think of putting them up is making an MDF ceiling tile, cutting a hole in it for the in-ceiling speaker, and hanging it from the drop ceiling suspension. Anyone have any alternative mounting that might work for a drop ceiling? Also considering getting another set of M3 on-walls, asking for the mounting post in the back so I could us a full metal bracket to hang from the joists above, then re-frame the drop ceiling around the speaker. Anyone have options for me that I can consider (other than drywalling the ceiling). Thanks in advance for any ideas.
