Who's Using Powered Subs for Lows?

Discussion in 'Amps and Cabs [BG]' started by Count Bassie, Jun 3, 2013.

  1. How do you run your system with a powered, or non-powered sub?

    I have an SWR SM-400s and Henry the 8x8. I won't sell the 8x8 if I can find a way to generate the heavier lows when I need them, which the 8x8 can't really do by itself. Not what I'm calling for anyway. The SM-400s may not be able to put out enough power run stereo, so a powered sub would be ideal I think. Don't want another head, I like the sound of this one.

    I'd like to run the SM-400s in 'Mono' to the Henry, and use the Send to get line signal to the sub.

    Info, anyone? All ears here, thanks.

    sub'd ;)
  3. Okay, that's just not very clear. Can you elaborate?...

    Powered subs with build in crossovers can go in the effects loop.
    Send full range to the sub, and it keeps the lows and sends back the mid/highs to the amp in the head. The amp in the head can get much much louder now, and it keeps all the tone. There really is no "tone" lows that come from the sub.
  5. I get that- cool! Thanks.

    I often times run a sub...it's fun :)
  7. You'll only need one of your 2x10 with a sub.
  8. Is this to say that all those speakers we use (8x10, 8x8 cabs) are just to get some lows out- that 'highs' really don't require much help? That would make a certain amount of sense, wouldn't it... so I don't "need" my Henry the 8x8 at all then...

    Starting a more electronica oriented project that would demand heavy lows (massive attackish...) and the idea of a powered sub into the FX loop sounds amazing... anybody actually uses it? other options?
  10. Taking 100hz and below to a sub takes a big load off. Certainly worth checking out the 2x10, my guess is one would do it. Fearful crosses over a lot higher to use the 6" mid.
  11. That is interesting. Smaller, more available punch, the sub takes the brunt of burden off. Hmm.
  12. You probably want a full PA with subs and forgo onstage low end. Having multiple sub systems is a recipe for mud.

    Count Bassie could be in the same boat.

    Once the lows are taken out of the mix, the highs and mids are easier to produce on their own. So a 210 may be all you want. I've used subs in my rig with mixed results: Without a specified crossover point where the "high/mid" cab takes over for the sub, things can get a little muddy. On the other hand, a sub is literally a low freq specialist, your lows may be a bit lower and stronger (not always). Then on another hand, if you are using a powered sub, you could get off with less amp, perhaps using your favorite combo for highs and placing the sub in the effect loop, as someone already suggested.

    P.A.s are intalled in the venues I usually play, so we don't bring our own... the proble with those small venues PAs is that they usually neglect the lows---

    I think the OP would be better served by finding a stand alone cab that provides him with the sound he wants.

    Yes, something to make his bandmates full of fear of his rig.

  17. :)
  18. The sub would only come out for gigs where there isn't adequate PA, or if there's no bass going to it (small, club scene)- like the other day when I played outside with no FOH at all. But there's a guy locally with an Ampeg 410HLF, and we've spoken.

    Anyway I'd run it from the FX loop like Seamonkey mentioned, and let the sub do it's own job with the 210 on top handling the rest. Only thing, would the full-range 210 still get the entire signal- even the lows as well?
  19. Clearer version of the question just posed:

    Can I run any cab on top of the powered sub, which is being sent to through the effects loop? Will the full signal return to the head and then go on to the 210- or whatever- on top, after it's passed through the sub's circuitry? Or will the lows that the sub passes be taken out, and what's left goes to the top cab?

    You need a crossover or else a powered sub with one built in.
