So i have read a hole bunch of negative stuff posted on TB about mixing cabs. And i have read nothing but how big of a P. O. S the siesmic audio cabs are, well granted they are cheap, but i got the SA 210 4ohm put it ontop of my 115 black widow:mixing cabs:and a P. O. S , with my mark 6 head, and let me tell you this rig sounds very very good. Good tone good punch good volume and very clear at any volume . so dont allways be so quick to put something down untill u have tried it, just thought i would put that out their. Keep rockin
