there are no such things like dumb questions,only dumb answers.
to get things clear,if you put the hr data from post 64 in hr,you should get fr graph of post 63, and thats is the one i moddeled.

Has anyone done any measurements on a built version of this to see if the response matches the predictions? I'm particularly interested in a comparision between the predicted and actual impedance response curves.

fitting speaker on baffle

Ok I want to mount both speaker on the baffle board but I am afraid the speakers surrounding might get damage when the cone is moving. Is they away to cut out the speaker hole on the baffle board that won't damage the speaker surrounding when the cone in moving.

measure the outside dimension of the surround(~7"),thats the size of the hole to cut
