Even 30 watt tube amp is way too loud to play in the majority of
residential situations.
I feel like every guitar player should get to feel the power of a
high gain amp, like a 100 watt Marshall stack once in their life.
I'd simply have amps in an isolated place facing a large field, with
a
small stage with monitors to hear with clarity as well.

To anybody who hasn't stood on a stage with massive,
towering walls of amplification power behind, in front
of and all around you while tens of thousands of
people do their best to make enough noise to counter
your massive audio thunderstorm... |
|

I haven't stood on a stage with a massive, towering anything (unless you count my bank overdraft from when I was a student). I still think this is a good idea though. |
|
| |
I've been on stage with Sturton standing behind me. Does that
count? |
|
| |
Only as something for the magistrates to take into consideration. |
|
| |
Well, with this idea you can. |

Amps are cheap compared to speakers and power
supplies!
100W all-valve guitar amps into 8x12" Celestion Vintage
30's is loud. So loud it doesn't make sense at first, most
venues have multiple kW PA systems, yet when you crank
up a full stack they barely compete. I thought valves
were magical for a while, but it's all in the speakers.
They're horrible in terms of frequency response, they
change the tone significantly, but they're soooo efficient
compared to a PA speaker. As an illustrative, but totally
unnecessary work through. A Vintage 30 has a sensitivity
of 100dB, so 1 W makes 100dB happen. A PA speaker
might be 85dB. A rule of thumb says you need double the
power for each 3dB increase. So to match the Marshall,
you need 5 doublings. 100>200>400>800>1600>3200W
amp. That's coincidentally where experience got us for
the vocalist's PA. |

Imagine the bull moose you'd attract, running moose calls through such a system (see link). Feed the whole village for the next three years! |

//huge lump of capacitive power to deliver bass peaks// |
|

Good caps are never cheap, Some Lipo batteries are
shockingly good at transient current delivery, I'm wondering
why there's no Lipo-enhanced amps around. |
|

Oh yes, possibly Meese, with such a loud, strong call... as we know: one goose, two geese, one moose, two meese; one mouse, two mice, one house, two hice. |

And of personal interest to you [Giblet]: one turkus, two turkii. |

Sorry about doing a zombie post (putting an old idea
up) but electricity to power speakers is for the weak.
You want to blow out windows, eardrums and shake
the ground, you're going to want to go with
explosions. (link) |

Tchaikovsky was way out front on this one. |

If you take a reasonable cannon, loaded with say, 1 lb of
black powder, that gets a cannonball to about 2000ft/s, or
600m/s in metrique. An average speed of 300m/s, 1m
barrel. Burn time in the order of 0.0033 s, so the power is
~1.5MJ, about 450 Mega Watts. Pleasantly loud music to
defeat the French by. |

It wasn't thousands of screaming teens, but maybe
800ish, and I... was not the guy with the Les Paul. I
played the keyboard. |
