To get an idea of how well those cabs will work for your choice of driver vs the original design spec you should compare the frequency response info for both drivers and also check to see if the cab designs and the driver freq responses are complimentary

Get the info for the cabs and the drivers and see what it tells you. If you are struggling then post links to the info here and PM me and I will take a look. I may take a few days to get back to you though 😉
