Hi. I've got a Fender Princeton Reverb 2 amp (awesome amp) and am thinking about replacing the original worn-out speaker with a Celestion Blue alnico speaker which is rated at 15 watts. Trouble is that the PR 2 is a 20-watt amp (or 22-watts depending what website you visit). Anybody got any advice about doing this? Can this be done or am I taking too big a chance? Otherwise, I will go with a Weber Blue Dog anlico rated at 30 watts. Thanks.
