Love my Taranis, but found that the speaker was tinny and not very loud. Also I had no bass at all out of the speaker. I found many upgrades for the speaker online. I ordered the speaker and made an adapter. It was an easy install, only took about 20 minutes. The kit is available at our store.
Take out the 6 screws holding the two halves together and split the case. Disconnect the wiring to the old speaker and remove the old speaker.
Then use hot glue to install the adapter.
Then solder in the speaker connector then glue in the speaker.
Put everything back together and you are set.
