    Has anyone done this? I'm thinking of small gigs - guitar-bass-drums jazz trio. I have a 300W Genz-Benz Shuttle head into a 4-ohm Eden 112. Could I connect line-out from the head to a small powered subwoofer, and would that help?

    I've noticed that the single 12 cab sounds great and full, but I don't think it disperses real low end very much (or very far). The added benefit of using a powered sub to augment this setup, is that I could choose to run it the way I mentioned above, or just run it off the P.A. when we want to run a P.A.

    Thanks.

    You'd be better off with 2 8ohm cabs. You need to push more air. I had the same amp a few years ago and it just wasn't enough using a single cab.

    You'd want a powered subwoofer that has a high-pass output. The Shuttle's effects loop send would go to the input of the subwoofer and the high-pass output would go to the Shuttle's effects loop return. This way you won't have your 112 and subwoofer causing unnecessary phasing issue. Also, it will take some of the low-frequency burden off of your 112 and allow for more headroom.

    The single 12 can get pretty darn loud when you take the demands of making low frequency off of it.

    I'd borrow or rent the sub and see how you like it before buying one. There is a guy on BFM's forum who runs a horn sub under a little Genz combo amp and can get crazy loud with that.

    Adfing a second regular bass cab would be a more practical idea but you're already at the 4ohm limit with the one you have.

    Thanks for the responses, and yeah, I realize this would be a bit of an unorthodox setup!

    It is a great suggestion to see if I can rent to try it out with my gear in a real band situation, I am going to see if I can do that.
