Hello everybody! I was wondering how much better was the SWR goliath series compared to the new Workingman`s Pro series. I have a a goliath Jr. and yamaha 1x18. Sounds good, buy i cant move the 18 for gigging. I may have the chance to trade the 2x10 for a Workingmans 4x10. How is the difference in souynd quality? (Pros and cons of both) How much volume can i have with the 4x10? how much lows? (i have a yamaha 500+500 power amp) Thanks for any input!
