HELP with locating knowledgable persons about TAD R-1


I have a pair of TAD r-1's. I bought a pair of a dealers demos as he was dropping the line, so he isn't a dealer any more so I don't bother him, but I have several questions and a minor issue to deal with. I have tried calling their Long Beach office(left several VM's with nothing in return) and emailing them at the address on the TAD website to try to find someone to ask questions. Does any one know a contact person? Thanks in advance.
