m, the two speakers are essentially the same but the crossover components are picked to a different tolerance, the woofers have a different amount of latex coating on them, the torque settings on the fasteners are set differently and the undercaots of the finish are different. a polymer coat adds mass to the mx-r which makes the cabinet a little quieter, the sound more continuous from top to bottom so there is more resolution.
there is an obvious difference in the way they sound because they are tuned differently.
the mmi is easier to get great sound out of while the mx-r does sound more right/better but you need a better system to get it out of them.
ok?
