You are describing a speaker that was made by Music Industries around 1999. They made a batch using the π name. After discovering this, I made them aware that the π name is a federally registered trademark, and they immediately changed the name of this product to "Prime." I don't know if they are still in production or not.The company "Music Industries" has no relation with π Speakers and their products are nothing like the π Speakers discussed here. The proprietors are nice fellows, but their products are wholly dissimilar.
