SORRY, NOT AVAILABLE AT THE MOMENT.
Here is the speaker box for making some noooooooooooooooooooise! Do you really want to listen to and feel the harsh repetitive kick boom sounds? Then this wood framed hard quarried rock speaker box is the one for you. You can choose 8 kick sounds, adjust WOBBLE parameter to make the beats more kind of like BEATS MUSIC, change the interval long or short and vibrate with boom! (iPhone only) Kick it whenever you want, e.g. while playing the piano, the drums, walking, singing and beatboxing. I hope you like it. Enjoy!
