I know that output works on a logarithmic scale (very similar to decibels, but the log is to different base... *scratches head*... I think), but how come valve amps are FAR louder than transistor amps? I'm pretty sure of this ater having played about with a 30 watt valve jobby, which had a 12inch cone, which was deafening!!! Now, my practice amp is rated as 50watt, it's only got an 8inch cone, it produces a fantastic sound with out having to go deaf for it... But it's still, FAR FAR FAR quiter! Why?
Does cone size really make THAT much difference?
or amps rated by power usage as opposed to output? which would make sense...
