I am being pressed into a bass role where I will need a bigger amp. I don't want to deal with a head & cab set up yet so I need a a combo that can deal with a church setting that can seat about 300 to 500 people. Celings can be about 20' high. I was thinking about an SWR Workingmans 15 and if needed I would get a 2 x 10 cab if extra punch is needed. Has anyone used this set up? The SWR should run at 200 watts with the extention cab. I'm not sure if this will be enough. Am I just dreaming or should I deal with the head & cab set up?
