The problem with most audio speakers is that they're not designed to irritate your neighbors to their full potential. Sure, you could point your speakers directly at a window or shared wall, or place it against a floor-mounted cast-iron radiator to send the sounds of Shakira directly into the apartment below yours, but doing either of those things can diminish your own listening experience.
Well, help is here in the form of wireless resonating speakers like the Mighty Dwarf, seen above, and the Mini Dwarf, seen in the video below. These diminutive devices sound like crap when played open-air, but attach it to virtually any surface--the floor, a window, or the sheetrock between apartments 2A and 2B--and you've got a party!
