I do not know the man that built these speakers. But I can't help admiring what he's done. The drivers appear to be a TangBand 871 and a Dayton neo tweeter. I don't know what the crossover looks like. It could even be a simple capacitor. A Sonic T-Amp and an MP3 player finishes the system. A variant would probably go great in an office, although I don't think I'd choose pink.
