Kodomo, be advised that if you move your individual drivers up and down then you need to do time realignment of your systems.   

You finding about the “drivers need some space” is kind of controversial. Let me to talk a little bit about the subjects. My experiments with the Macondo topology suggested that the dependency to space for individual divers to a great degree depending from the proximity of the entire speaker to boundaries. For instance if a speaker is located close to the side or back wall (back was is more critical) then you can feel very well the vertical position of the drivers. It is not that more space is good or less space is good but rather you do feel impact of moving drivers up and down. IF however a speaker is well acoustically detached from the walls (let say it is 6-8 feet to the horns with diffusers on the walls) then musing the driver up and down impact sound less. You still will have impact in driver integration but it will be rather “equally good” then “one better than other”.   

A few words about your frequencies response. You have slightly shallow response under 70Hz. That little peaks that you have at 70Hz masked it out but it is there. With response like this you will not be able to get luxury slow bass, you will not have proper “space” and your MF will have no lower harmonics support. Take some crappy $50 subwoofer, set it in phase with 35Hz line up the LF to be 2-3dB over the MF. Get the impact it make to the overall sound. Now, get rid that crappy subwoofer and try to get the same response only by more honorable means….
