DISCLAIMER: I am not offering legal advise - just my opinion.
They have the right to protect themselves for the use of the words: N.E.A.R ARMADILLO SPEAKERS
But Drew is using the words ARMADILLO SPEAKERS and in my opinion, this is not infringing on their mark.
If they owned the mark "ARMADILLO SPEAKERS" and Drew started a site called "Drew's ARMADILLO SPEAKERS", then I believe they would have a case. Drew, I do not believe you even need a disclaimer.
Not only do I believe I am correct on how a court would judge this case, but if someone with a mark like N.E.A.R ARMADILLO SPEAKERS has rights over a person using a domain name called ARMADILLO SPEAKERS the whole system is in grave danger of abuse.
N.E.A.R ARMADILLO SPEAKERS did not register the mark "ARMADILLO SPEAKERS." Had they wanted the rights to that mark they should have registered it. I believe this is a case of bullying. I suspect Drew is right in that they are trying to get him to "give" them the domain. Drew, I highly advise you to get legal advice and don't give in to pressure unless a lawyer advises you to do so.
