The WOW Thing is designed to improve the sound of your speakers by making your speakers sound taller and wider than they are. Run sound output through the WOW Thing and into your speakers and you are supposed to hear a definite improvement.
More Eh Than Wow
A friend of mine got a new computer system
recently that included a set of Harmon Kardon
HK-195 speakers. When she played something
through them I said "wow," I had never heard
anything that good come out of a computer
speaker. Judging by its name the WOW Thing is
aiming for a similar response.
