Garman; I think you got the idea from the fact that bass requires lots of power and SS is current driven. Thats how most people I hear understand the SS/bass thing. I need to ask; how loud do you go? Unless it's house or beats what could require such phenomenal power? The JBL is pretty efficient right? My GC runs the theater 4's to plenty loud, I can't stay in the room if I turn it up. I think the same amp for all drivers; every mixed bag I have heard had an annoying discontinuity apparent in the music.
