Think of thermal compression at 1 watt at 84db vs. 1 watt at 99db!!
I’ve heard the difference hundreds of times…… the 84db (low sensitivity) sounds stuffy and congested with no dynamics. Doesn’t really matter what topology
When you figure out the difference in the cross section of voice coil wire and inductor wire in crossovers you get back to us.
I did the work for you on resistors. 50-100ppm for good ones. 200-400ppm for cheap. 25C on the cheapest resistors is 1%. Maybe it makes a 1/2 percent difference in the circuit? I doubt even the most expensive speakers are built to that tolerance and they won't use cheap parts.
A lot of people making up stuff to suit what they want to believe here.
