Re: Do Speakers Like To Be Pushed?
So the distortion that comes with volume is a lot of stuff going on. There is the fact that more air is physically moving, the fact that ears/brain perceive the frequencies of loud sounds differently than low volume sounds, The fact that we perceive certain midrange frequencies as louder than other freq's to begin with (and the guitar is centered in the midrange), the tubes overdriving and creating 2nd and 3rd order harmonics, the speakers might be breaking up too.
The thing you're almost certain not to get with your setup is speaker distortion but not everyone even likes speaker breakup so I'd say for now don't sweat it. If the sound is loud and your amp's running on high you should get most of what you're after, shouldn't by a long shot be "undercooked" sounding.
Sometimes for really tight rhythm sounds you actually don't want an amp at full tilt, with speakers breaking up. It can sound too loose, mushy, or woofy or not clear enough. Sometimes you can get really heavy, clear, but saturated sounds from a 100W high-gain amp with a good master volume set really low. And because the power amp isn't anywhere close to topping out, when you ask the amp to deliver power, it delivers it with punch and immediacy.
So... it all really depends on the sound you want!
