How To Make Sealed Subwoofer Box - QUICK DIY BUILD

Sealed car subwoofer enclosures are very cheap, easy and quick to build. They can produce accurate, clean and tight low end frequencies. Sealed boxes usually smaller than their ported counterpart which make them ideal in small vehicles like hatchback sedans. Having installed this into the minivan and listened for a while, I am actually starting to like sealed subwoofer enclosures now more than the ported ones. The bass tones are more defined on most genre of music.

Here's the steps in making a sealed subwoofer box:
00:00 - Unboxing of the Pioneer TS-W261D4 10" subwoofer.
00:15 - Create and account and you can copy this Tinkercad layout and design
00:25 - Box-Port Design II sead enclosure calculation.
00:35 - Wipe MDF edges and surfaces with wet cloth before gluing. Water will make the MDF swell a bit and will ensure tight and secure bonding.
01:00 - Gluing and pin nailing the back panel.
01:10 - Cutting perfect subwoofer holes using router and circle cutting jig.
01:35 - Rounding just the front edges to give the box a more streamlined look and feel.
01:40 - Wood glue can be used to air-tight seal the seams inside the box. No need for extra silicone adhesives.
01:50 - Strengthen the box by finishing it with pin nails using electric nailer.
02:05 - Charcoal black carpet as final touch.
02:35 - Most important task in building sealed subwoofer boxes is to add and fill up with polyester fiber fill and/or felt fiber fill. This is essential to make the enclosure appear bigger to the subwoofer. So absorbing any resonance produced inside the sealed box.
02:50 - Stick the rubber gasket that comes from the subwoofer on the rim of the mounting hole to ensure air tight sealing.
03:00 - Wire the sub to its lowest impedance by parallel wiring to draw the most power it needs. In this subwoofer, wiring in 2 Ohm is the best option.
03:25 - Mount the subwoofer using T-nuts and Carbon-steel allen hex bolts.
03:40 - Final impedance check is 2.2 Ohms. Perfect!
03:50 - Final product showcase.
