I don't know. Usually around here people aren't discussing in-cieling setups. However, here are some aspects for you to consider.
Subwoofers are heavy devices. Mine weight 100 lb each. Granted these are heavy ones, but the drivers alone are also heavy devices.
Subwoofers tend to be large. Of course how large depends on the size of the driver, whether you want a sealed (larger) or ported design, and how low you really want it to go. Mine are 2 cubic feet internal volume with a 12" driver, in a sealed enclosure, but are servo-driven - otherwise the box would have been a different size. How much space do you have between your false and hard ceilings?
It is generally accepted we cannot detect directivity below around 80 Hz. So placing a subwoofer on the floor might make life easier. If aesthetics is the constraint, consider buying a kit, such as Rythmiks, and building a subwoofer that looks like an end table or other decor piece. I bought these kits, but because I wanted to build a really heavy, sturdy enclosure.
I hope this triggers some thoughts.
