I also thought that because I will power the subwoofer with separately, I may not need the extra power of the ML 33 over the ML 33H, but the melon (football like mid bass driver) is the real magic in the mbl 101, IMHO. But I am not sure if the bass control that the ML 33 has over the ML 33H is applicable to the melon (mid bass driver). Do you happen to know the answer to that last concern? Your response to this, and the previous post, will be greatly appreciated hk_fan.
