These lightweight speakers, by Fashion Nation, are made of 100% recycled materials and they come in a variety of colors and shapes. They fold flat for easy transportation and only cost $15 each. The idea is excellent - however, they should know that sound causes paper-like material to vibrate and vibration is a major factor that could degrade the audio quality. I am skeptical about the performance though. As a conclusion, I suggest using a more sturdy recycled material and reduce the folding gap in order to create a vacuum-like speaker.
