Hello fellow thumpers, I am fortunate to have the Fender Bassman 300 pro, all-tube 300 watts. I run it through an Ampeg SVT 8X10 HLF, rated at an astounding 1600 watts, 3000 peak (!) It sounds great, but even with all that power the head can drive the speakers just at 3 or so on the master volume, not distorting, just clearly pushing them.Thing is, I would like to try 2x15's with the head. I have always heard (as in been told and actually heard with my own ears) that tube power is stronger than solid state. But how does this relate to the manufacturer ratings of cabinet power handling? I have found that many 2x15's are rated at around half what my 8x10 can handle, so they are like 800 watts, 1600 peak. Does this mean 800 "solid state watts" or what? Thanks, I'll hang up and listen.
