I’m sure this has some legitimate purpose
I’d check my Amazon account to see when I bought this, except I won’t because I don’t care. This was one of several random audio devices I bought under the mistaken impression it would allow me to turn a dual-channel 2.1 sound system into a surround sound system. I bought the speakers at an NYC hardware store run by two elderly Italian men, one of whom was the spitting image of Mario, and the other was the spitting image of Luigi. They claimed it was found in an old warehouse. It was not possible to turn it into a surround sound system.
