Why you should do this mod
The Taranis is a great radio. They did a great job with almost everything about this radio. However they used a pretty poor sounding speaker. It has low volume and not much bass. Its ok for basic voice commands, but when it is louder or if you want to play music it is lacking.
This mod will put a much louder and better sounding speaker in there. The cost? $4 and a pill bottle.
Parts You Will Need
Remove the stock speaker
(Sorry, didn't get a photo of the stock speaker) We need a round section that fits the speaker, and a round section that fits the Taranis speaker mount. You'll need to open up your Taranis and remove the stock speaker to do this. The Taranis opens by removing a few screws in the back. Once open you can pull/pry the speaker out. It is glued in place. Then disconnect the plug that attaches it to the main board. You then have to remove the cable with a soldering iron.
Solder the old connection in place
Solder the wires onto the speaker. But which way should it go? This is VERY important. If you do it the wrong way the speaker will be out of phase. That means it will move inward and not outward as it should. To determine correct polarity/phasing take a AA battery and tape two wires to the ends. Then touch the wires to the speaker power tabs. You have them on the right polarity when the speaker moves out. Then solder the red wire to where you had the positive wire, and brown to negative.
