@erik_squires i genuinely wasn’t trying to advocate for a “yes, they are worth it” or a “no, buyers are being gouged” position. I was just trying to see, because you have actually done the work, to what i am guessing is a pretty high level of success, as how much R&D is involved in going from passive to active. And we know that a manufacture will try to recapture R&D cost (plus profit margin on it) quickly. (For extreme examples, see pharmaceutical pricing in the US.)
So, for example on your point about crossover network, cabinet and drivers, is it the case that one can pretty much just add in an amp (after deciding which one matches best), or are there modifications (even modest one) to those features that going active requires? And if no material modifications are likely needed, how hard is it / how many trials are needed to choose the right amplification?
