First off, this is the first performance Thumper we've made available to the public. Not only can you start a show anywhere, but 4 people can connect to this Thumper: a singer, guitarist, DJ etc. You can also lay this bad boy on it's back with our custom 3d printed enclosure for the mixer made by our neighbors, Kapow! 3d. And don't forget, it's still got a rechargeable battery lasting you up to 10 hours! 

As you may have learned from a certain HBO show, there’s always someone ready to claim the throne—you can’t be complacent, you have to be constantly on the lookout for usurpers. In terms of looks, sound, and all-around awesomeness though, King may have set the bar too high for any other portable audio system to challenge it.
