So I upgraded from an old analog AVR to a budget Denon w MultEQ. And wow. I was way off. In just about every aspect of what I was "trying".
I officially give in. My brain does not work the same way as all of you amazing engineers with your HUGE mathematical brains.
I may be making it harder than it is, but I have struggled long enough.
I wish there was a laymen explanation of sound, how speakers actually work (1 kudo for me, I was able to use WinISD fluently), REW, & how REW helps in particular from Low to High. No offense but just about every "manual", tutorial, or help article goes on & on & on in amazing detail so guys like me end up being conditioned to skip around help manuals & forum posts trying to find answers in an endless cycle of failures.
I am afraid I am going to fry my newly built VBSS that took a gaggle of weekends to finish. I had no idea that a li'l ole thing like "sound" was so complicated. From phase, transfer functions, waterfalls, room acoustics, sound theory to something as simple as wrapping my head around how sound disturbs air particles in a room.
I am going to go back to what I am good at so I can get my self-esteem back. (Or at least interested enough to know it through & through.)
Carry on my sound and acoustic prodigies. I am going to get out while I still can.
