Home High Efficiency Speaker Asylum

Need speakers that can rock with just one watt? You found da place.

Room modes sparse under 50Hz.?

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.
