Wagner,
You can look at the overall dimensions of the speakers on our site and then take off about 1 1/4 inches to get the cutout dimensions. In general, a 6 1/2 inches speaker should fit there but if you could go up to an 8 inches and trim out a little bit of drywall, you`d have a perfect fit.
We don`t list the cutout dimensions of speakers because we’ve found that if given the option, people will cut their holes before the speakers arrive. Then, if for some reason they don`t like the speakers, or they go out of stock and they have to change, they`re stuck.

What in-ceiling speakers do you have that will fit in an 8″ opening using the dog ear clamps?
Thanks,
