There are 6 screws under the rubber feet on the bottom. Removing them allows the bottom plate to be removed, and then from there, the front panel, front cover, and battery compartment.

Two passive radiators are present inside the device. They're fairly heavy but rubberized, and they resonate and are tuned for low frequency reproduction. These move a LOT when it's playing. 7-10mm per side.

This is great, thank you Larry. I'd wondered about the possibility of upgrading the battery to one that lasts longer between charges but I had no idea how to open the case. It didn't occur to me that the screws would be under the rubber feet!
Larry,
My mini connector for dc into the board has broken. Replace connector or the whole Board? Where can I get a Power Board?
Where could I find the replacement speaker? My right speaker is buzzing a little on certain songs. Thanks!
