I have an SWR Goliath Jr II that needs speakers. The originals are expensive and hard to find. What else works well in these? Anything in a Neo would be even better. This is the same age as the cab in question, with the diagonal grill: I'd also consider moving the speakers from my Super Redhead into the Goliath Jr and putting new ones in my Redhead. Neos would be great in that, shaving 10-15 lbs off that thing would make a huge difference.
