    Is it possible to use a QSC or Crown amp to power a 4x10 cab? Anyone tried it?

    yes lots of people do it. Don't forget you're gonna need a preamp too.

    I have another bass amp I still plan to use. Will the Direct XLR out work as a sufficient preamp?

    How will it sound?
  4. I have a very same, yet different question.How about using a sans amp with a powered speaker? Is it the same?

    Not usually. Is the DI output pre or post pre-amp? If it's post, it should work. Sometimes it's switchable.

    The pre-amps job is to boost the voltage to something the power amp can recognise and cleanly amplify. The output from most basses is <1 volt, too low to get max power from a power amp. The pre-amp will bring it up to >1 volt, producing a juicier signal for the power amp.

    Some amps have a specific output for "preamp out". You may want to check yours.

    A lot of people do it. I do it (running to a bass head). You may have to keep the level control down lower than if you were going to a power amp.

    yes using a power amp is the thing to do, lots of headroom and your choice of preamp
    fwiw, bass sounds wonderful thru most good and durable pa speakers as well
