There's no such thing as a source with 0dB losses. That's a line source. Too bad it's oriented the wrong way.
Very impressive if you don't know how speakers work. Needless to say, I'm not impressed.

That's only because they haven't stacked the boxes to infinity on each axis yet and replaced the atmosphere with an ideal gas. I give them an A for effort though.

I give them a 'D'. If they'd taken the effort to read a book on acoustics and learn the right way to do it they'd have gotten a better result with 1/3 the speakers. Then they might have gotten an 'A'.
