Quick question...polk 6501mm components are 2.7 ohm...if i remove the passive xover from the set and go active are each tweeter and woofer 2.7 or are they going to be 6ohm each?
They aren't in parallel the way you think because the crossover splits the signal so the amp only sees one speaker at a time.
Typically, tweeters have a higher impedance than the woofer and the crossover accounts for it. You can measure DCR on each driver and approximate the impedance.
