Re: Tonal differences of 50W v.s. 100W w/ 2 pulled tubes?
Play a speaker with 100db's sensitivity, and then hook up to to 97db speaker back to back, and it's a quite noticable difference.
If your playing 100db speakers with a 100 watt amp, just changing to 97 db speakers is like changng to a 50 watt amp in terms of loudness, or vis a vis. That doesn't mean they will be the same in terms of tone though.
The db scale is like the earth quake scale, it's not linear. There may not be much difference between say 60 and 63 dbs, but farther up the scale there might be a huge difference in precieved loudness.
The amount of wattage required to produce a doubling of loudness is also not linear. It requires a squaring of wattage to create twice the loudness, all else being equal. Hence a 25 watt amp sounds twice as loud as a 5 watt amp, and it would take a 625 watt amp to be twice as loud as a 25 watt amp. A 100 watt amp is only twice as loud as a 10 watt amp.
