A high-quality car sound system is an expensive pleasure. But some of its components can be made by yourself, for example, you can assemble a box for a subwoofer.
Necessary
- - multilayer plywood;
- - PVA glue;
- - self-tapping screws;
- - sealant;
- - carpet;
- - electric jigsaw;
Instructions
Step 1
The first step is to choose the shape of the subwoofer for which you want to design the box. There are several types of “subs”: closed type, subwoofer with bass reflex, band-pass type, “sub” with an additional radiator. The most common type of subwoofer is the closed type.
Step 2
Once you've decided on the type, download the JBL SpeakerShop software. Open the Enclosure module. In the dialog box that appears, select the geometry of the subwoofer, for example, Prism slanted front, and enter the parameters of the trunk. The program will automatically calculate the dimensions of the hull of the future "sub".
Step 3
Take a sheet of plywood and mark the side walls of the cabinet. Use an electric jigsaw to cut them out. Connect the walls of the case with PVA glue, and then screw with self-tapping screws, in increments of 5 cm. Wait for the glue to dry. Fill the gaps between the walls with sealant. Remove its excess with a knife.
Step 4
Fill the body of the future "sub" with water and check for leaks. The enclosure of the subwoofer must be sealed in order to achieve high sound quality. Drain the water and re-seal the defects and crevices with sealant. Be sure to dry the case with a hairdryer.
Step 5
Mark the location of the speaker and punch a hole with an electric jigsaw. Grind the edges of the hole so that you do not damage the speaker in the future. Also make a hole for the wires.
Step 6
Cover the body with carpet and glue it with silicone glue. Overlap the edges. Once dry, trim off the top edge. You will get a neat and inconspicuous seam.
The subwoofer box is ready.
