As the title says, how does it work?
A 4th order bandpass has one sealed chamber and one ported chamber with the driver installed in the wall between them, so far so good. But when the cone moves into the ported chamber, the pressure in the ported chamber increases, and the pressure in the sealed chamber decreases. Why don't they cancel each other out? My logic tells me this should be a very ineffective design with wasted potential, but this is obviously not the case.
2 sealed chambers cancel each other out, but add a port in one chamber and magic happens... or does it has something to do with phase response?
