I am pretty ignorant when it comes to amp/cab issues, so maybe you can help me out. Right now I have a Fender BXR300R head with a custom 2X8 custom cab with aluminum cones. It works great as a monitor for me at church, but if I ever did anything else I would be totally underpowered. I have a friend that is selling a SWR big ben (18")for $250, and I was wondering if it would be a good match to go with the 2X8. I had thought a 15 or a 2X12 would be a nice fit, but I have heard the big ben is a very responsive 18. Is that a good price for a big ben, and would the combined wattage of my two cab (about 550 watts) would be a bad fit for my head. Do heads sound better when matched with the wattage of the cabs that is equivilent?
