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.-- Giblet, Feb 21 2019 Bull Moose, undisclosed location https://www.youtube...watch?v=E9epiN0X_d8 [Sgt Teacup, Feb 21 2019] Forget about electricity to power speakers...

...you haven't lived.
This is a great idea.-- doctorremulac3, Feb 21 2019 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.-- DrBob, Feb 21 2019 I've been on stage with Sturton standing behind me. Does that count?-- MaxwellBuchanan, Feb 21 2019 Only as something for the magistrates to take into consideration.-- 8th of 7, Feb 21 2019 I have not lived...-- 2 fries shy of a happy meal, Feb 21 2019 Well, with this idea you can.
Sort of.-- doctorremulac3, Feb 21 2019 //I made a kilowatt amp once, a nice mosfet affair, but only tested it with a dummy load.//
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.-- bs0u0155, Feb 21 2019 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!-- Sgt Teacup, Feb 21 2019 //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.-- bs0u0155, Feb 21 2019 No not meese!-- Giblet, Feb 21 2019 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.-- Sgt Teacup, Feb 22 2019 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)-- doctorremulac3, Feb 22 2019 //you're going to want to go with explosions.//
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.-- bs0u0155, Feb 22 2019 It wasn't thousands of screaming teens, but maybe 800ish, and I... was not the guy with the Les Paul. I played the keyboard.-- RayfordSteele, Feb 22 2019 random, halfbakery
