i go off of measurements. if your multimeter cant tell the difference, your ears most certainly cant.
audiophoolery aside, one thing that confuses the shit out of me is biamping in speakers.
from my electical engineering class where we designed crossovers, you end up with a high pass portion and a low pass portion. their response depends on the load, and the load for one crossover is basically made up of the speaker AND the other half of the crossover (not for first order crossovers, though).
so what i dont get is, when you remove those bus bars from a crossover and connect amps to the now seperated tweeter+woofer, how does the crossover retain its normal frequency response, considering the load is entirely different?
alternatively, how do youdesign a crossover so that removing 2 wires (hot and ground) will completely isolate the tweeter/woofer from the entire crossover?
thats some wizardry right there. my 685's support biWIRING, but not biamping. they sound like absolute trash if you try to biamp. and biwiring is just a flashy way to waste wire.
