My 2 set of springs(4 boxes under each speaker and 4 boxes on top of each speaker and those then directly under the load) are slightly differently compressed by a difference around 8 pounds( the weigh of the speakers+ the load for one set of boxes and only the load for the other set of boxes)... This fact is important....
Then the distribution of the resonance pattern inside the speakers are modified so much that it is possible to immediately hears the difference.... It is not a difference in the direction toward bass frequencies or high frequencies, even if they improved, instead more a direction toward better mids frequencies and better timbre tonality and a better imaging then....A naturalness impossible for me to get with only one set of boxes under the speakers even if the load is fine tuned for them....
I think no one has use the spring boxes in this way, then even with springs internal speakers resonance has a destructive effect that goes unnoticed .... I realize that after my experiment....Adding a second set of boxes decrease internal resonance interferences...
No cat or children allowed in my audio room, and even my wife give me the dust cleaner to use it myself here.....I think that only ghosts of great composers go trough my room but their spectral wandering pose no threat to the equilibrium of this tower of springs, plates, and slabs of concrete.....I will look for some load more dense and compact than concrete..... :)
