You should probably start a new thread for some of what you posted tacoma. The main reason I argue for passive is cost, and by that I mean if someone takes the time to learn about crossover networks and how to build them themselves properly and for the desired effect then they will save alot of money. The easy way is active and yes I have run both and I have to say for me at least passive is way better, but I don't run rears and I don't run speakers all the way down my doors even where they will not be heard. The goal of any system should be that you have speakers from high to low covering all frequencies that music is reproduced in and that those speakers are filtered in the correct frequencies properly. Most passives cover this well enough, however for me I have and am now designing my new system to go from 30-12k hz using 8"s 4"s and 3"s and building my own passives with 400rms on each set. I guess everyone has there opinion and everyone's situation is going to be different and there are too many variables when telling someone that passive is better then active. I am defintely NOT saying that passive is better becuase neither is better then the other but more or less that it depends on what your money is like, how much time and skill you have. I think the OP had is answer a few post's ago so I'll shut up now!
