Can This Be Done!! I’m about to ask something kind of out there, now I want you to work with me on this. I’m sure it’s some science or physics or something that will keep this from ever happening. How this crazy thought of mind came about is, different tunes on subs have compromises. This now brings me to my question. Can one design a HT with (powered or not) subs, @ different tunes, to all work with each other putting out maximum SPL’s? For i.e. (collocated or not) Sub A: tuned 25hz Sub B: tuned 20hz Sub C: tuned 15hz Sub D: tuned 10hz (i know i'm asking a lot on this one) X them to overlap for a seamless transition, and Equed from 100hz all the way down to 10hz or lower! Remember no compromises far any loss of SPL! So can this be done or am I a dreamer??! Oh, and of course the subs most sound good and be articulate. What would be perfect, if one sub could do it all. This thread is for educational and fantasy of the a perfect sub/sub's, that could do it all. Now let's have some FUN!
