Remove the audio chamber by unscrewing the 6 screws with a Phillips #2 screwdriver.

It’s a sizeable audio chamber for such a small speaker. Upon opening it up, you will easily identify:

5200 mAH lithium ion battery

Port tube for boosted bass

Drivers x 2

You’ll also notice that all the cables (and there are a lot of them) are shielded with foam to prevent rattling.
