    passive = does not have it's own amplification
    powered = just like it says

    With a passive sub, you either need to supply an external amp, or the sub will need to be run off of powered lines (speaker level vs preamp level out) from your receiver. The drawback to running directly off the receiver is that you will be drawing a significant amount of power to drive the sub in addition to your other speakers, which will reduce available headroom for all of your speakers. Another drawback is that you will not be able to use your receiver's bass management with this setup, as you will need to run your mains as large with the sub connected inline.
