SEALED ENCLOSURE Building a Sealed Enclosure: 1. Build a sealed enclosure with internal L x W x D as specified for your woofer (See recommended enclosures for your woofer). Use 3/4” thick MDF for 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. Using the supplied template, trace the appropriate circle and mounting hole pattern for your PowerClass C2 subwoofer on the baffle board.
SEALED ENCLOSURE Sealed Speaker Diagram Internal dimensions should be calculated to determine the correct box volume. Be sure to allow for speaker displacement and extra bracing (if used).
PORTED ENCLOSURE Building a Ported Enclosure: 1. Build a ported enclosure with internal dimensions of LxWxD as specified for your woofer (See recommended enclosures for your woofer). Use 3/4” thick MDF for the enclosure. Be sure to use wood glue and silicone at all joints to ensure your enclosure is sealed properly. Air leaks will affect the performance of your subwoofer, even in a ported enclosure. 2.
PORTED ENCLOSURE Ported Enclosure Diagram Internal dimensions should be calculated to determine the correct enclosure volume. Be sure to allow for speaker displacement, extra bracing (if used), and port displacement (only the length of the port that is INSIDE the enclosure). It may be necessary to angle the port to fit your design. To calculate the displacement of the port: (Outside) Radius2 x 3.14 x Length of the port that is inside the enclosure.
BANDPASS ENCLOSURE Building a Bandpass Enclosure: 1. Using 3/4" thick MDF, cut out all the panels to build a divided enclosure with internal dimensions of LxWxC1 and C2 as specified for your woofer (See recommended enclosures for your woofer). 2. Using the supplied template, trace the appropriate circle and mounting hole pattern for your PowerClass C2 subwoofer on the baffle board. 3. Cut the speaker and port holes from the baffle board with a router, using a guide or template whenever possible.
BANDPASS ENCLOSURE Bandpass Enclosure Diagram PO WE RCLASS TM Internal dimensions should be calculated to determine the correct enclosure volume. Be sure to allow for speaker displacement, extra bracing (if used), and port displacement (only the length of the port that is INSIDE the enclosure). If the port is very long, it may be necessary to run the port through the sealed chamber into the ported chamber. To calculate the displacement of the port: (Outside) Radius2 x 3.
