Most tube amps soft clip so effects of not enough power are
not as unpleasant. Other than that, a watt is a watt.
What's different is how far a watt can be made to go. Soft
clipping helps. Limited bass extension does as well. These
are things that can help make a speaker seem more
"efficient". You need exponentially more power to deliver
a lower frequency at a certain volume level. That's
physics....basically how things work no matter what anyone
might claim. That's why a table radio with just a few
watts and limited bass extension might sound clean within
its limitations at a louder volume.
