    the speaker that has lower frequency response (40hz) can give u more midbass
    the speaker that has lower sensitivity (85db) will need a more powerful amp.

    biamping is connecting a 4ch amp to a passive crossover that has 2 inputs 2 outputs.
    bi-wire is like your dvc sub (one amp to 2 terminals)

    average manly voices = 2 - 4kHz

    average feminine voices = 3 - 8kHz.

    Female who has 3kHz voice are those who drinks a lot, get wat i mean :D j/k

    desmond, mid-range driver is generally crossed at 3.5khz. So above than that, the tweeter will take over up to 20khz.

    vocals will come from both tweeter and midrange, so u shouldnt use that to compare.
