Disclosure: I own 3 RBH in-walls that I use for home theater and I have owned RBH subs.
The brand has always lacked mainstream press acceptance. I'm sure there are gentlemen that support this site that would testify that it is not easy to win press attention away from Wilson, Magico, KEF and the few others that hold to it dearly.
It is also not about value, technology, build quality or "house sound". To become a "house-hold name" in the speaker business you have to win at marketing first (think BOSE).
RBH has always been about value and quality. I assume they make a living as they sell to lot of installers and have a nice product line. As for me I am part of the "exotic" O.B. fan club and RBH has always made conventional boxes (although good ones).
If they were market savvy, they would support A.C. they have a untapped market here that they don't even know about.
