That's why they are so audible -- not dense enough!Probably three room modes under 50Hz. in a typical room.
Maybe four in a very large room.
These lowest frequency bass resonances are also the most powerful.
You control harmonic distortion by using mutiple high-XMAX drivers for a dipole. Not cheap. Not small. But subjectivelky better bass quality than monopole speakers in most rooms. Especially smaller rooms.
There is no room gain from a pressure source unless the room is unusually sell sealed (like a car with windows closed) which is very rare. You may ask Earl Geddes for details from his experiments.

- Let's consider a typical 20 x 15 x 8 room -- maybe you may be somewhat partially right about monopoles below 50Hz.! - Richard BassNut Greene 09:41:08 02/07/07 (0)
