"Jose" wrote Well, when an object passes through the air, does it not compress the air in front of it (and rarefy the air behind it)? This is how speakers work. Those are all pressure changes. Air is pressurized behind the speaker, just as well as the air in front of it. That is how bass reflex speakers work. -- Jim in NC
