There is a car, but the music does not suit. What to do? First of all, you need a high-quality music center, well, to it a powerful amplifier with corresponding speakers, the so-called subwoofer. In the box they can be one, and two, and three.
What box for a subwoofer can we do with our own hands ? For some reason, many do not like store subwoofers. Or the sound does not suit, or are expensive. In a word, we will do it ourselves.
It is necessary to come up with the form of a subwoofer, dimensions, design, and only then all this can be put into practice. The fact that it is necessary to purchase high-quality low-frequency dynamic or dynamic heads, I think, is not worth talking about. This is understandable, without speakers there is no subwoofer.
The case in the form of a truncated pyramid is considered the most optimal and universal. It is noteworthy that its rear wall is made with a bevel of 23 degrees. This is due not to the sound characteristics of the device, but to the design features of the car. Many people think how to make a box for the subwoofer so that it takes up as little space as possible in the trunk. This 23 degree bevel is the solution to this issue. Just the rear seats in the car are located at that angle.
A closed box is best for this type of acoustics design. But there are more complex options for making a subwoofer. For example, bandpass and bass reflex. The difficulty is that not every amateur will be able to calculate and configure such equipment. Need a specialist. It’s good if you have a friend, and if not, you’ll have to pay, but we want to make a box for the subwoofer with our own hands for reasons of economy. You can use an open subwoofer. In cars sedans, the trunk is an ideal enclosed space that can serve as a natural box.
Experience suggests that over time, and improved music. So, for example, experts performed calculations, from which it follows that for the DS250 speaker you need a closed box with a volume of about 30 liters.
After the calculations, we begin to think about how to make a box for the subwoofer, which fits perfectly into the design of the car. First, draw a drawing, looking at which we will have an idea of what we get in the end. A 23 mm thick chipboard is suitable for the front wall, and a 20 mm chipboard is better for the side walls. For the back wall, you can also use chipboard - 20mm. After the preparations are prepared, we begin to collect. You will need PVA glue. We coat the glued surfaces and tighten them with screws. It is better to take a step of 5 cm. Next, after the box is assembled, put it with the front side to itself and fix it. With a pair of compasses, we outline the desired hole, and then with an electric jigsaw we cut out a circle corresponding to the diameter of the speaker. Do not forget to make holes for the wires.
To box for a subwoofer with your own hands was made better, you need to consider some nuances. For example, due to the high pressure created in the duct, the acoustics begin to choke. To prevent this effect, you need to install a screen. This is a small box greased with glue and screwed with screws to one of the side walls.
After the work done to make the subwoofer, we begin to refine it. The external state of the subwoofer also plays a role, albeit not the main one, but still. For casing, you can use a carpet. He will need a meter and a half. As glue, nitrolac can be used. Then in the Carpet from the front side we cut a hole for the speaker.
Next is the installation and fixing of the speaker with its subsequent connection to the music center and the on-board network. Thus, we learned how to make a box for a subwoofer with our own hands at low cost.
