I'm thinking about trying an active/powered sub, in addition to my Acme low B2 rig...just wondering if anybody has had luck with this type of setup. I'd be playing very bass heavy live electronica, funk, and dub styles. Our band uses an active Yorkville sub sometimes for small gigs. Its good for kick drum and bass in a medium room http://www.yorkville.com/products.asp?type=71&cat=31&id=109 That seems almost small enough to lug around to gigs myself Mackie makes a good one too. Im thinking about the smaller ones though, just as an extension of my normal rig. I could even put it across the stage. what do ya'll think?
