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.
