Even if it disappoints you to hear that Rock It portable speaker system lacks amplifiers, you would have a second opinion once you see and experience how this device functions. This compact speaker system can be connected to audio devices like small time Mp3 players to iPods and Laptops. Although it works as a speaker, it doesn't have an amplifier, but makes up for this drawback pretty impressively.

Basically, the speakers offer great quality and decent amplification if they are fixed to items which are hollow. More hollow it is, the greater will be the volume. Cardboard boxes, inflated plastic bags etc will be able to throw back the sound, amplify it and hence increase the audibility as well. An ordinary plastic bowl also offers the best result.
