Q. What are the three different kinds of speaker cabinets?

Answer

Enclosures that are hermetically sealed (or closed): This is how a room that is completely shut off operates. There is no way to access the rear of the speaker since it is entirely enclosed. The air contained inside the enclosure functions as a spring, which enables the movement of the cone to be more precisely controlled. The pressure within drops as the speaker travels away from the microphone, while it rises whenever the speaker comes closer to the microphone. Ported enclosures, often known as bass reflex enclosures: A hole, also known as a port, may be seen at the front of this enclosure. This port is responsible for maintaining an even pressure within and outside the speaker. When the diaphragm goes back inside the speaker, it raises the internal pressure, and this pressure is then sent out of the speaker via the front port. The sound waves that are emitted by the speaker are strengthened as a result of this motion, which also significantly improves their efficiency. 3Band-pass enclosures: Band-pass boxes are a specialized kind of ported box that was developed specifically for producing the most slam possible. The sound waves are exiting the box on the side that is ported and the woofer is installed inside of a dual-chambered box, with one chamber being sealed and the other being ported. Within a certain frequency band, the noise that is produced by the port is notably heightened in volume.
