Upgrade Speaker on Taranis X9D Plus TX

by Oscar

The stock Taranis speaker is pretty bad in terms of sound quality. It’s sufficient for what we use it for, but if you are looking for better sound quality, especially for background music, you might find this tutorial useful.

After this speaker upgrade, my taranis sounds a lot better than the original one. The upgrade speaker sounds much clearer, has a much stronger bass. When I turn the volume up, I can even feel my TX vibrates with the bass, pretty cool :D

Hardware Requirement

You will need the following hardware for this upgrade:

  • 2W 8Ohm Upgrade Speaker
  • 3D printed speaker adapter
  • Hot glue

The upgrade speaker is widely available, simply search for “8 ohm 2W speaker” in eBay or Amazon (for example), and look for a similar speaker to the one we used in this tutorial. These speakers cost about $3-$4 each.

But they are a lot bigger than the existing speaker, it won’t fit directly in the Taranis (36mm in diameter).

Therefore you will need a 3D printed speaker adapter. There are tons of designs on thingiverse, just choose one that you think will fit the best.

Process to Replace the Taranis Speaker

The whole upgrade takes only 20 mins.

  1. Take out the Taranis battery (always do that when you are working with the internal of the radio)
  2. Remove the 6 screws in the back of the TX and open the case
  3. You should see the speaker inside the front shell. There are only 2 wires connecting the speaker to the board
  4. Unplug the cable, and remove the original speaker (there is a little bit of glue holding it in place), don’t worry breaking the original speaker, we won’t need it anymore (hopefully)
  5. Unsolder the speaker wires, and solder them on the new speaker (watch out for polarity, red goes to positive, brown goes to negative)
  6. The 3D printed adapter is going to slide into the hole, you can secure it with hot glue. Then the speaker is going to sit on top of the adapter, again secure it with hot glue
  7. Now you can plug the speaker back in the board

Put it back together, and there you have it!

We are not sure yet at this stage :) unfortunately i don’t have the QX7 to check.

Sorry, I’m late to the comments, because I’m new to the hobby.
The speaker on the QX7 is VERY thin and size is restricted by the transmitter’s PCB.
That being said, I’ve created a work around that WILL allow you to add an upgraded speaker for the QX7 (assuming you aren’t using the module bay)
No permanent modifications needed if you have (access to) a 3d printer. I’ve created a box and link to the speakers at thingiverse.

Hope this helps, and great site Oscar!
