Do you really believe this drivel?
1. The build house buids what the speaker manufacturer asks for. Sometimes they offer engineering services, but I know for a fact that Dan designed all his speakers.
2. Just because you have never seen the Parthenon, doesn't mean it doesn't exist. There are pictures and videos on the web proving it does exist, in working order.
3. You really should talk to Scott, or the engineers at Eminence before making such claims.
4. If XBL^2 was a rip-off of other technologies, then a patent wouldn't have been given. The patent office does extensive research on each technology applying for a patent to be sure it is an original idea. That's the reason why it took so long to get approved. This fact shows how fabricated your above claims are.
