I'm wanting to add an extension cab to an SWR WorkingPro 2x10c I recently acquired as my portable rig (it's got wheels!). I bought the combo used because my lead sled multi-cab rig + bass was taking me 3 trips to load and unload, and while I love it for playing out, it is very cumbersome for practice and rehearsal. As a 5/6 string player, I have really come to enjoy the musicality of 12" drivers (I know, super subjective). I will mainly be searching used market for either a used Workingman's 2x12 (similar in design to Avatar and GK's 2x12 cabs) or a Goliath Jr. 2x10. While I know the Goliath's are technically "better" cabs, the Workingman's series really isn't too shabby. I've heard a few complaints about their factory tweeters vs the Goliath series, but high quality phenolic and titanium tweets aren't very expensive if I determine that to be a weak point. Is there a reason to look at one in exclusivity to the other? An additional 2x10 (per Goliath Jr.) would be a very respectable rig, but the appeal of some 12s backing up a B string isn't insignificant. Low B players experience especially appreciated.
