I would measure it if I can. I am currently in China and don't have the speaker with me. As mentioned before, I wanted to get it made while I am here. I could measure it when I return and have it made next time I am back in China.

I did try to contact Axiom. No response to my request. So I am stuck right now until I return to the US or some provide me some information. I have tried to search around for this information and have no luck. I will try again.
