I can't remember off the top of my head, but I'm sure someone will. Or just go to the Hard Truckers web site and call them. They are great people and will tell you any dimensions you want to know.

Thanks!

11-1/16" (or 11.0625) was what I had for three different 12" speakers (non- JBL's)

Sounds like 11-1/6" may be sort of a "standard" opening that could work for many front loaded speakers.
