I bought 4 of these bins, i thought they were loaded with beyma GT 200.

because of the ts parameters are about the same with the original driver from JBL, they will do fine with no adjustments.

By unscrewing the front of the bins, it seems that 2 bins were loaded with beyma's 18G550, in this case are not suitable for this bin.

By recalculating the ports, can it be suited for the beyma 18G550?

can anyone calculate this?
