Or theoretically it can be. My build really has no indepth audio filtering and its not made with the highest quality of parts so its not exceptionally great. I made it more as a novelty. Another difference with the traditional speaker is that is produces sound in all directions making it more like real sources of sound. Below I've included a video of it being demonstrated as well as a look into the build and how it works. If your not particularly intrested in the specifics of how it works then I wouldn't watch the second half of the video as it gets kinda boring. If you are however curious of the insides, there are still pictures and descriptions below.
