Once you learn how to craft speaker enclosures, you will be able to create ones that match the sound quality you want. A typical dual speaker box design is a closed, vented enclosure. This article describes how to make a closed cabinet that separates the sound waves from the front and rear of your speakers for improved bass.

Steps

1. 1 Determine the size of the speaker enclosure.
   • To find out the dimensions of a speaker, see its template.
     • Templates and other documentation should be included with your speakers. If the template was not included, contact the manufacturer or measure the speaker yourself:
   • Determine the depth of the speaker cabinet (size from front to rear) by measuring the speaker depth and adding 5 cm.
   • Use the speaker height and length values ​​as the internal cabinet height and length.
   • Multiply the depth by the height and length of the hull to find out its internal volume.
2. 2 Check if the resulting internal cabinet volume matches the speaker manufacturer's recommended volume.
   • Resize as needed until you reach the desired values.
3. 3 Add the thickness of the wood to the dimensions to calculate the outer dimensions of the enclosure.
4. 4 Measure the height, length, and depth of the accessible spot where the speaker cabinet will be installed to make sure it fits there without issue.
   • Use the measurements to sketch out a speaker cabinet depending on where you want to fit it.
5. 5 Build a speaker box.
   • Draw the template onto the Fibreboard (Fiberboard) from the outside of the cabinet.
     • Also mark the round holes for the speakers and connectors. The required dimensions can be found on the speaker template. If there is no template, trace the outline of the front of the speaker on the front of the cabinet and a 5 cm hole on the back for the connectors.
   • Use a power jigsaw to cut out parts of the body.
   • Use a router to cut out the round holes.
   • Sand all sharp corners.
6. 6 Fasten the speaker cabinet together with 2.5 cm x 2.5 cm wood strips.
   • Cover 60 percent of each inner corner with wood planks.
   • Screw the bar onto the fiberboard.
7. 7 Place the cut pieces against each other to make sure they are the same.
8. 8 Pre-drill all holes and apply a small amount of glue to the joints when assembling the case.
   • Use furniture clamps to keep the cabinet parts flush.
9. 9 Place the speakers in the cabinet and check if they fit.
10. 10 While the speakers are in the cabinet, mark where you want to drill the holes to mount them.
    • Pull out the speaker and drill holes in the places you indicate.
    • Wait for the glue to dry.
11. 11 Apply silicone sealant to the internal seams and holes to keep the housing sealed.
    • Leave the case for 12-24 hours until the silicone sealant dries.
12. 12 Assemble the speaker box.
    • Connect speaker wires.
    • To minimize resonance, cover the back, top, and bottom of the cabinet with a 2.5 cm layer of polyester.
    • Insert the speakers and connect the connectors to them.
    • Screw the speakers to the cabinet - this will secure them.
    • To ensure that the housing is sealed, seal all gaps with silicone sealant.
    • Wait 12 to 24 hours for the silicone sealant to dry.

Warnings

• Do not make a speaker cabinet with walls of the same size. This shape reduces the efficiency of the speaker.
