Your ears ( or some other hearing/sensing mechanism in your body )
"feels" large objects around you, and I think they will definitely "hear" relatively large upperbass horns mounted in the ceiling, even if no music is playing... It will definitely change the way your ears/body defines the "space" of your listening room, since they will be felt as being "over" you as compared to "in front" of you... 

Actually this, was very much the fact (and I though about it a lot) that initially leaded me to the idea of me ceiling mounting. You see, we can locate the sources in lateral plane easily but our ability to locate sources in vertical plane is severally diminished due to the positioning of our ears. I noted long time ago that the LF line arrays that are approaching
In their total high of the room’s high always loaded the rooms with special sound that I never was able to obtain from a regular single-source LF section. So, the separating of the lower-upperbass horns and upper-upperbass horns in space across vertical plane kind of creates this attract of super tall line-array.

Also, and this is more imperative, in our playbacks we never, or very rarely, reproduce “the space above our heads”. In any Concert Hall we have 50-100 feet (or infinite amount) of space above us and this “space” acts as acoustic buffer-randomizer-resonator. This large amount of “space” is also act like a lowpass filter, subduing the HF but being totally transparent for the LF’s pressure waves. This waste mass of enclosed air has own LF harmonics that we do not really hear but still those harmonics modulate “something” when music transmitted to us through this “space”.  I would say that out experience of music are always “spiced” with the space above us. So, the presents of a “large object above you” is not necessary is bad thing, quite a contrary – the “alien” LF source “above us” works very well. If I could (space limitations + many other issues) I would mount a pair of a high power sub-low frequency modulator to my sealant…. Hey, do you want be my neighbor?

Well, certainly I would not propose this solution as a panacea but I feel that it is a fruitful direction; at least it worked very well in my room.
