What is an infinite baffle and how does it work?
An infinite baffle is a type of speaker enclosure that uses a sealed compartment to separate the front and rear sound waves produced by a subwoofer. This design allows the subwoofer to operate in a sealed environment, which can improve its low-frequency response and overall sound quality. The infinite baffle works by creating a barrier between the front and rear sound waves, preventing them from canceling each other out and allowing the subwoofer to produce a more accurate and powerful sound.
In an infinite baffle setup, the subwoofer is typically mounted in a sealed compartment, such as a wall or a floor, and the sound waves are allowed to radiate freely into the surrounding air. This design can be particularly effective in home theaters and music systems, where a strong and accurate low-frequency response is critical for an immersive listening experience. However, it’s essential to note that not all subwoofers are suitable for use in an infinite baffle, and some may require specific modifications or designs to work effectively in this type of setup.
Can any sub be used in an infinite baffle?
Not all subwoofers are suitable for use in an infinite baffle.
