What is a sealed box and how does it work?
A sealed box, also known as a sealed enclosure, is a type of speaker enclosure that is completely sealed, meaning it has no openings or ports. This design allows the speaker to produce sound by moving air within the enclosure, creating pressure waves that are then released through the speaker cone. The sealed box works by using the speaker’s backwave energy to reinforce the frontwave energy, resulting in a more efficient and accurate sound reproduction.
The sealed box design is particularly effective for producing low-frequency sounds, as it allows the speaker to move more air and create more pressure. This results in a tighter, more controlled bass response. Additionally, sealed boxes are often used in applications where space is limited, as they can be designed to be more compact than other types of enclosures.
