Slot box for Pride Eco 12 subwoofer with 37 Hz port setting
Content
This time we decided to bring to your attention a drawing of a box for a Pride Eco 12 subwoofer. This is a budget subwoofer, with its pluses and minuses. It has a hard bass, the size of the box is larger than average. But there is something that surprised us.
Firstly, the subwoofer plays loudly for its price and power, and secondly, it has a more musical frequency response, which allows it to win back both high and low bass with the same volume.
Box detailing
A small number and a simple shape of the subwoofer cabinet parts make it possible to make them in a home workshop or order them at any furniture company. In the first case, you can be proud of your skill, and in the second, save time and nerves. It should be noted right away that the most important parameter that should be paid attention to is the solidity, structural strength and tightness of all subwoofer connections, this is much more important than appearance.
The dimensions of the parts are as follows:
number | the name of detail | Dimensions (MM) | PCS |
---|---|---|---|
1 | Right and left walls | 350 x 406 | 2 |
2 | Back wall | 350 x 618 | 1 |
3 | front wall | 350 x 562 | 1 |
4 | Bass reflex wall 1 | 350 x 314 | 1 |
5 | Bass reflex wall 2 | 350 x 350 | 1 |
6 | Rounds (Both sides at 45°) | 350 x 52 | 3 |
7 | Rounds (One side at 45°) | 350 x 52 | 1 |
8 | Lid and bottom | 654 x 406 | 2 |

Recommended Amplifier Settings
We understand that a large number of people visiting our portal are non-professionals, and they are worried that if they are configured and used incorrectly, they can render the entire system unusable. To save you from fears, we have made a table with recommended settings for this calculation. Find out what wattage rating (RMS) your amplifier has and set the settings as recommended. I would like to note that the settings indicated in the table are not a panacea, and are advisory in nature.
Setting name | RMS 150-250w | RMS 250-350w | RMS 350-450w |
---|---|---|---|
1. GAIN (lvl) | 60-80% | 55-75% | 45-70% |
2. Subsonic | 27 Hz | 28 Hz | 29 Hz |
3. Bass Boost | 0-50% | 0-25% | 0-15% |
4.LPF | 50-100hz | 50-100hz | 50-100hz |
*PHASE - smooth phase adjustment. There is such an effect as the subwoofer bass is temporarily behind the rest of the music. However, by adjusting the phase, this phenomenon can be reduced.
Before installing the amplifier, read the instructions, in it you will find what cross-section of the power wire is necessary for the stable operation of your amplifier, use only copper wires, monitor the reliability of the contacts, as well as the voltage of the on-board network. Here we have described in detail how to connect the amplifier.
box frequency response
AFC - graph of the amplitude-frequency characteristic. It clearly demonstrates the dependence of loudness (dB) on the frequency of sound (Hz). From which you can imagine how our calculation will sound, installed in a car with a sedan body.
Conclusion
We have put a lot of effort into creating this article, trying to write it in a simple and understandable language. But it is up to you to decide if we did it or not. If you still have questions, create a topic on the "Forum", we and our friendly community will discuss all the details and find the best answer to it.
