Messing With the Audio Third Rail

fiogf49gjkf0d The fact is, typical "stereo" L and R separation is mostly an engineering hodge-podge to begin with, and any further messing with it will be very much settled by ear, whether at line or at speaker level. Yet James Bongiorno set out to "solve" the problems with a practical application of his own, proprietary, theoretical solution to the mess he insisted was/is inherent in "stereo" recording and playback. And "phase issues" are what he meant to address.
The "theory" is confusing, anyway, whether adding "parts" of left to "parts" of right, and vice-versa, or "simply" adding together/blending the left and right channels to make a center channel. I have planned for some time to have a main, multi-driver center channel, and I even have a 3rd MA-9S2 sitting there, ready to drive it, and I will do this sooner or later. Meanwhile, I have been told repeatedly by folks who should know that there is more to summing left and right channels "correctly" than just tapping a channel and/or strapping leads together, whether at line or at speaker level. In fact, I first approached James Bongiorno about designing a transformer-based stereo channel sum-er. But by then B was already convinced that he had discovered the only viable answer to this in his Trinaural processor, and he literally would not "waste [my] time and money" on a "non-solution" like I wanted. He did offer to build a Trinaural processor for me, and he also offered me a money-back guarantee; but at the time it just seemed like "too much" to me.
Sadly, although I have listened intently to all the experts, I have yet to hear a simple explanation for the "channel thing" that I really understand. Apparently, generic stereo phase "issues" make any sort of summing mix-and-match a fairly wild hit-and-miss proposition, due to electrical and (ultimately) audible summing and cancellation that might or might not be wholly predicted or predictable (unless you're James Bongiorno...). Naturally, I won't let reality nor concerns about it stop me from trying a center channel, and of course I will tell all here, apropos.
