[QUOTE="helotaxi, post: 1903960, member: 550915"] Passive is frequency division done after the amplifier. Active is done before the amplifiers. With a passive setup you will run one amplifier channel on each side of the front stage and the frequencies are divided between the mid and tweet by a series of caps and coils. In an active system, the frequency division is done at line level and the correct frequency is sent to a dedicated amplifier channel for each individual driver. Passive is simple to set up, just connect the passive crossover to the amp and run wires to the drivers. It is also cheaper since you only need two channels of amplification for the front stage. Active is more complex to set up but more flexible as well. Unlike a passive setup where the crossover frequencies are fixed, and aactive setup allows you to adjust the frequency to give you the ability to fine tune the response curve. Also you have individual level control for the mids and tweets. You additionally have the ability to run time alignment for each driver to optimize the soundstage. The drawback to active is cost. You need a channel of amplification for each driver you plan to use. This can be done with a multichannel amp of several two-channel amps but running a 300W four channel in a two way active setup will not give you the same volume or head room as a 300W two channel run in a passive setup.
