Quoted from colofan:The redesign process that I will do is :
Characterize the current system both electrically and acoustically.
First is to examine the backbox and down firing speakers both impedance and also an pink noise rta spl measurement at the distance where the user of the pinball will be standing.
Measure the lower box to determine volume and also how "leaky" it is with all the perforations in the playfield and all the leaking around the seams. This will affect mostly the efficiency of the system.
After that I will then start to model the environment with "LEAP" and look for a better drivers. to replace the current models.
Install new drivers with new crossover designed. Test the system and see if some "tweeks" are needed for phase response mostly.
What will be an outcome? A custom speaker set and/or rheostat and/or built-in amplifier?
