![]() ![]() This means the forward wave travels outward into the room, while the backward wave travels only into the box. These enclosures are completely sealed, so no air can escape. The most common type of enclosure is the sealed enclosure, also called acoustic suspension enclosure. Different enclosure types have different ways of handling these "backward" waves. But, since the diaphragm is moving back and forth, it's actually producing sound waves behind the cone as well. When we looked at speaker drivers, we focused on how the vibrating diaphragm emitted sound waves in front of the cone. If you simply placed a driver on a table, the table would vibrate so much it would drown out a lot of the speaker's sound.Īdditionally, the speaker enclosure affects how sound is produced. Enclosures are usually built with heavy wood or another solid material that will effectively absorb the driver's vibration. Everything's in one unit and the drivers are kept in the right position, so they work together to produce the best sound. On their most basic level, they make it much easier to set up the speakers. ![]() These enclosures serve a number of functions. ![]() In most loudspeaker systems, the drivers and the crossover are housed in some sort of speaker enclosure. In a sealed speaker setup, the driver diaphragm compresses air in the enclosure when it moves in and rarefies air when it moves out. ![]()
