    Do powered speakers work as normal passive ones if you don't plug in the power or does this damage the internals of the speakers?

    Thanks in advance.

    Most powered speakers only take mic/instrument/line level signals, not speaker level signals.
  3. Are you talking about speaker cabs with built in power amps? Passive speakers are something else entirely.

    If the cabinet that you're describing has a power amp built into it, the only input is a line level from a preamp or similar.

    You can't use them like a passive speaker cabinet unless you somehow disconnect the internal amplifier from the speaker. I wouldn't think that the OEM would include such a jack.
  5. Hmm, I think I understand. Are you talking about just not plugging the power section into the wall? I doubt it will work at all without modifications.
  6. Hey, can someone name examples of powered speakers please?

    A lot of PA speakers I've seen, like the one's in my school for example, are powered. They plug the mixer straight into them, and the speakers are plugged into the wall outlet.

    Way back in the late '60s/early '70s there was the Acoustic 360. It featured a preamp on top and a powered speaker cabinet. The cabinet featured a single 18 in. driver in a folded horn cabinet with a 200 watt power amp in the bottom.

    That's the amp that was used by Larry Graham, Jaco, John Paul Jones and many others.

    I know of a guy who built his own powered 1x10s and then drove them with a SansAmp Bass Driver...or he might have used the Acoustic Driver for the sweepable midrange control.
