How a horn amplifies sound (hint: Impedance matching) https://tube.loping.net/videos/watch/c25c1cf9-c9bd-45d8-90fa-2d6367e6ed1e A horn-shaped speaker is louder than an equivalent speaker without the horn. This fact doesn't violate physics because the horn is acting as a matching device between the speaker and the air around it.
