AH: Can you tell me a bit more about the anechoic chambers? How large are they and how low in frequency are they able to measure?
B&W: We do not disclose this information to the public. 
Sounds like they're not very proud of their anechoic chambers.
Can't even disclose the size of their anechoic chambers?
Very lame!
Makes me wonder if they are really going to be doing any real research. I bet everything will be kept secret and they will continue to "not disclose this information to the public".
