A box that houses a subwoofer is called a subwoofer enclosure. Sub boxes come in a variety of forms, but they all have the same purpose. Increased bass is what we hear from the subwoofer’s air pressure, which is built up by a sub box.
In order to fully enjoy the bass in your music, it is essential to add an enclosure. Without an enclosure, the subwoofer sounds weak or nonexistent because the sound waves from the speaker’s back side cancel out low frequencies from the front.
Rundown of The Steps Involved in Building a Subwoofer Box
| Item | Details |
|---|---|
| Box Dimensions | Height: 11.5″ Width: 12.5″ Depth: 10.5″ |
| Depth Measurements | Depth 1: 3.5″ Depth 2: 6.5″ |
| Volume Calculations | Rectangular Box Volume: 1,509.375 cubic inches Wedge Box Average Depth: 5″ Wedge Box Volume: 1,031.25 cubic inches |
| Conversion to Cubic Feet | Rectangular Box: 0.873 cubic feet Wedge Box: 0.597 cubic feet |
| Adjusting Box Volume | Compare the volume of your box to the manufacturer’s recommendation for adjustment. |
| External Dimensions Adjustment | Add back 1-1/2″ to the internal dimensions for the new external dimensions. |
| Building Materials | MDF Planks: Used for building the subwoofer box. |
| Step 1: Cutting the Boards | Measure and cut main pieces of MDF for various box sides. Use a table saw or have the MDF cut at a hardware store. Seven pieces total: top and bottom, two sides, back, and front panels. |
| Step 2: Draw the Circle | Use a compass or template for marking the woofer cutout on the front piece. |
| Step 3: Prepping the Front Panels | Fasten identical front pieces together with glue and screws for double thickness. |
| Step 4: Assemble the Box | Glue edges and press pieces together; then clamp until screws are inserted. Pre-drill screw holes to prevent MDF from splitting. |
| Step 5: Attaching the Final Sides | Use clamps to align the box while attaching the last two sides. |
| Step 6: Cutting the Woofer Opening | Drill a hole to fit a jigsaw blade, then cut out the woofer opening. |
| Step 7: Adding the Terminal Cup | Create an opening for the terminal cup using a hole saw, then install securely. |
| Step 8: Test Fitting the Woofer | Drop in the subwoofer to ensure it fits properly. |
| Step 9: Seal the Interior | Run a bead of caulk inside the box for an airtight seal after assembly. |
| Step 10: Installing the Subwoofer | Use rope caulk for sealing beneath the woofer frame; connect speaker wire before final assembly. |
How to Make a Subwoofer Box Sound Deeper
Stuff pillows into the sub box! Stuffing the box will make it appear larger than it actually is. This may seem contradictory, but how can adding stuff to a space increase its volume and space? As the sound waves pass through the stuffing, it slows down the air inside the box, which effectively lowers the tune. There are many intricate explanations available online. Even though you can effectively make the box smaller and tune it higher by packing it tightly or using a lot of foam, you still get boom-boom instead of thump-thump.
