SEALED ENCLOSURE Building A Sealed Enclosure: 1. Build a sealed enclosure with internal L x W x D as specified for your woofer (See page 10). Use 1” thick MDF (medium density fiber board) for the baffle that the Subwoofer mounts in, and 3/4” thick MDF for the rest of the enclosure. Be sure to use wood glue and silicone to ensure your enclosure is sealed properly, as air leaks will affect the performance of your subwoofer. 2.
