There are too many shuttle posts to count-I've read many but not all so my apologies in advance if this has been covered. I see many guys are using 1x12 with them. I also have seen the concerns regarding enough headroom. I just got the 6.0. I played it though my older 8ohm SWR Goliath JR and it sounded very "flat" I then plug into my 4 ohm HT322 and it sizzled. Is any one running 2x 8ohm 2x10 cabinents? I am lookiing for a bit more cabinet portability as well as headroom and it seems like this might work. Thanks!!!
