This post aims to connect with friends who have spare subwoofers at home and enjoy DIY projects. It’s also about reusing old items for a bit of eco-friendly creativity. For this project, you’ll need an active subwoofer (one with its own built-in amplifier) along with a 2.5mm three-pin adapter and a multimeter.
Here’s a visual guide to what you’ll be working with:
The 2.5mm three-pin adapter looks something like this:
The wiring might vary slightly depending on your specific setup, so use the multimeter to double-check.
Now let's dive into the connection steps:
First, plug the 2.5mm adapter into your Xiaomi console and attach the white plug to the active subwoofer. You'll notice that the subwoofer starts producing sound immediately. However, this connection doesn’t require any specific recognition from the Xiaomi host.
Once this initial step is done, the subwoofer will begin functioning, but the bass from the Xiaomi console will still play simultaneously. To fix this issue, we need to refine our setup to ensure only the subwoofer handles the bass output. Follow these steps:
- Get a 20K resistor.
- Cut the red wire from the subwoofer and connect one end of the resistor to the common terminal and the other end to the red wire.
Here’s a visual representation of this modification:
After completing this adjustment, the bass signal from the Xiaomi console will no longer interfere. The low-frequency sounds will now exclusively come from the subwoofer, and the Xiaomi host will properly recognize the subwoofer, allowing you to adjust its output settings.
I hope this guide proves helpful!
