If this were true, I'd be doing it, but I have yet to hear any modern equipment that sounds like the old monster cabs and huge amps do.
I don't care what the crowd or soundman thinks of my rig. More often than not we've played places where we never need a single bit of PA support. Telling the soundguy he can take a break because we're about to crush everyone in the room without his PA usually isn't a problem. We have more problems with venues letting us fill their room with fog than we do getting them to let us play at the volume we want. And do you think we're not playing for crowds into our style of music? It's not like we ask to be on quiet coffee shop gigs and show up with a mountain of bass gear. We play appropriate venues, with other heavy bands, although we are definitely the loudest heavy band in our area. But that's the point of this genre of music. Volume and vibrations so intense it makes everyone in the room zone out. If it runs some people out (which it rarely has) it's nothing to us.
My rig is about 8 feet wide. Drummer sits to the left of it...
And for what it's worth, it takes us about the same time to set up as it does any other band. Drummer always sets his stuff up as much as he can somewhere else in the venue, and as far as my rig, three of my cabs are on the floor and I only have to lift two and then stack the three amps in the middle. Hooking everything up is a breeze since I know what cords go where and can almost do it with my damn eyes closed.
And so everyone knows, who may not know or understand. What most people in this thread have said is "big" is my "too small" in the genres of music I play. Absolutely massive air movement is a must. Sometimes while playing, my vision blurs from the soundwaves hitting me to give you an idea of how loud I'm talking. It's not negotiable for us, it's part of our show. My friend Ashley who isn't even into our genre of music said seeing us live is like getting a full body massage. And that's the point.
So if I'm an extreme case and rarely run into trouble doing what I do... then what the hell is the problem with the guys here running tube amps into 2x15's or 8x10's?
Your right is someone elses wrong and this applies everyone here including myself.
