BUILDING THE ENCLOSURE
•
Determine the dimensions of your enclosure.
•
Be certain the box you have designed will fit into the location you have
chosen.
Sometimes making a cardboard box with the same outside
dimensions is helpful.
•
Use 3/4 inch thick Medium Density Fiberboard (MDF) or High Density
Particleboard. It is preferable to cut the wood with a table saw to ensure
straight, even joints.
If a table saw is not available, a circular saw is
acceptable.
•
Use a "T" square to verify precise right angle gluing.
•
Use a high quality wood glue and air nails or wood screws to assemble the
enclosure. Elmer's® woodworker's glue and Weldwood® work well. To
guarantee an airtight box, seal each inside joint with silicone sealant.
•
For Sealed Enclosures, stuff the chamber with 50-75% filling (approximately
1.5 pounds per cubic foot) of fiberglass insulation or Dacron®.
•
For Vented Enclosures, staple 1 inch thick fiberglass insulation or Dacron to
all walls of the enclosure except the baffle to which the woofer is mounted.
•
Use the supplied gasket to seal the woofer in the enclosure and eight(8)
wood screws or T-nuts and bolts. Progressively tighten each of the bolts or
screws to prevent warping the woofer frame.
•
Use slide-on connectors to attach speaker wires. Do not solder wires to the
provided terminals as this may cause damage to the factory wire
connection. This may also void the speaker's warranty.
