This stuff has been stuck in my mind for some time now, working around in there against my ongoing experience, against what I am now running. The goal is a more dynamic presentation with better spectral balance, with the emphasis on LF and [more] correct harmonic development top to bottom.
At this point I am not at all sure it is possible to do FR with one SET amp, at all. Somehow, everything I model winds up seeming to need at least two amps per side, with one amp just for LF. This notion is based on my cold, objective assessments of the "LF" I now get and mental "simulations" of what it would take to get enough LF energy in my present room to effectively balance off the SPLs presented in the present power band my system provides.
In this case, I mean LF on a par with the best the rest of my system has to offer. While I presently use BR for efficiency, it would be nice to have the LF integration and solidity provided by a sealed system. And I am pretty well convinced by now that this alone makes FR SET all but impossible.
Just now I am thinking for each side: four 15" bass drivers (sealed?); one Supravox GMF 285; 1 de-whizzered Reps; 1 modified Selenium 324 tweeter; 1 Audiphon ribbon.
All of a sudden, we're looking at five channels per side!
But at least we don't have to develop each horn, too...
