12" Sealed Empty Subwoofer Enclosures Boxes

12" Sealed Empty Subwoofer Enclosures Boxes

Sealed enclosures reproduce the low frequencies more accurately than ported enclosures because the air inside the box acts as a shock absorber, allowing the subwoofer to move back and forth in more control. The sound waves are reproduced more accurately than with a ported enclosure, but the subwoofers may require slightly more power from the amplifier to get the woofers to move as much as they would in a ported enclosure. Sealed enclosures are generally smaller and easier to build because there is no port to tune. You build the enclosure to the proper specification for your chosen subwoofer(s).
