 One question to your response. You mentioned the resonance of 80Hz is too low for this horn and to raise it to 110. What benefits does this usually bring, this equalization of resonance to horn cutoff? 

It is hard to explain in words. Generally if you match the resonance with your horn rate or bring it to a very close proximity then you have slightly different texture of bass. Sound becomes less hallow, softer, more meaningful and stickier to the room. You will get very minor gain from horn but it is not the objective. The main point is that bass become like it is not out of absolute phase, if you know what I mean.  There is a catch however. If you set the precise matching of resonance and horn rate then you might want to review it with time as the driver will get softer with time as it will break in.  
I think it is very educational to set the driver in the proper resonance and to spend some time to hear it. Then open up some back chamber and to hear how sound will be changing as the resonance frequency will be dropping. As you get your personal sonic reference of what happen with bass you will be able to make your own judgment.
