'Blow up'' the sound quite literally, by inflating, plugging in, and turning on the world's first inflatable speakers. The Ellula Hot Air Speaker System is like no other! It is the only audio product in the world to combine NXT with inflatable technology. Hot air speakers are manufactured to the highest quality standards to bring you the best in portability, audio outdoors, at home with your pc or gaming console or simply anywhere with your portable audio player. With the inflatable speakers, the sound resonates up through the base of the speaker, and broadcasts in all directions. The audio signal is converted into vibrations via NXT exciter, the sound vibrations are then projected into the rigid surface at the base of the inflatable producing high frequency sound, and the sound vibrations also resonate through the flexible PVC wall producing low frequency sound! Set it up in the center of the party and everyone will be able to enjoy the music, from any angle.
