Tube stack for arena rock band!

i found this in a tele thread somewhere else and its really important!

--------------------
Rounding off the decimal points, here are the frequencies in Hz, or cycles-per-second:

4-string bass:

E - 41
A- 55
D- 74
G- 99
(Hi G @12th fret - 198)

Guitar:


E- 82
A- 110
D- 146
G- 196
B- 247
E- 330
(Hi E @ 12th fret - 660)

Harmonic tones will be in multiples of those frequencies, doubling for each octave."
--------------------

It shows that the low E of the tele into a typical 12" speak is 82Hz so i think i im going to run everything from there and up to the soldano 100w to the full 812 stack on top. Everything lower (including up to whatever "tube harmonics" introduce) that goes to the alembic pre and crossover then SS mega watts for the folds and 18s. that would get more power exactly where i need it (the feedback and shatter i want in the feel of the ric when i ram* the pic into the strings with tortoise). *edit "strum". i couldn't think of the word when i was writing it the first time.

That is cooler than I thought at first.

What I just realized is that there is a perfect note. The increase in the number of hertz to increase to the next 4th increases with each increase.

That means that a hertz vs note graph would show a logarithmic curve.

And, as you go higher and higher and higher - eventually it will take a billion additional hertz to get to the next 4th.

And then you get to a point where adding a trillion more hertz won't get you any higher.

Once you add infinity hertz, you hit the perfect note.

keep in mind that for both bass and guitar you're really hearing more of the second harmonic, so that's 80 and 160 Hz respectively for their low E's.

When you're playing with active crossovers (biamping), you ultimately want to let your ears decide where the xover frequency should be.

That said, your reasoning is sound and would be a good place to start. Likely you'll want to bump up your xover frequency closer to 160-200 Hz. But you'll know what's right when you hear it.

^maybe, but for what i need its like what's going to push the speaker cone the furthest and produce the most spl to hit the ric? whats that going to be, whats going to make the strings explode like we've been talking about since last week?

So the perfect note is elusive then? Like a mathematical singularity? Makes sense...

with what you're talking about you're already in that zone: where the speakers are working most efficiently at where they sound best. Just a matter of the right amount of watts.

Best to run bass to effects (if you're using any) to the active xover, then from there that splits the frequency bands to the proper bank of amplifiers and drivers.

You're close. Go get that Soldano stack and the low freq cabs of your choice* and try it out.

*Edit: though you've been given a lot of advice already on some proper 70s vintage low end warriors, ahem. What are you waiting for?

Uhhh, you're missing something. When you move up into increasing frequencies, you leave the audio spectrum, move into radio waves (ulf, lf, hf, vhf, uhf, etc.), into infra-red, light waves, ultra-violet, x-rays, gamma rays and beyond.

Cosmic Rays is where it's at.

If you want strings to explode, i suggest a speaker cabinet big enough to have a door which you and your bass can fit inside.

Speaker cones made of 4 x 12" square hardwood panels all facing inward, driven by valve modulated hydraulic rams supplied by a 250kW 3 phase pump.

[DEL]Darn, you're right.

I forgot that this thread is based on facts and not on fantasy.

My apologies.

Carry on!

:bassist:[/DEL]

EDIT!

My apologies for apologizing!

Munji, you just gave me the key to unlocking my half baked idea!

Instead of going UP in frequency, we need to go down. WAY down.

Start going down by 4th's till you go down to, lets say: One Trillion Billion Million x 10 to the 10,000th power 4th's.

You can never reach zero, as we know - and now what do we have?

An Arena Destroying Earthquake!

Now...that is the sound the OP was looking for!

:cool:

I know you think you are kidding, but I have worked in the vibration analysis field, and it's pretty common to excite structures to determine resonant frequencies. Truly large structures do use some of those hydraulic rams referred to (also demi-seriously?) earlier. There was a case of an earthen dam being excited into structural failure and collapse - people died. Italy, IIRC, probably early '70's.

Structural resonances can be devastating. The Tacoma Narrows Bridge failure is classic and well-documented:

Doesn't one of them turn you into a spider?

That would suck....you'd be stuck with living in a water spout, and every now and then, the rain would come down and wash you out of your house.

If you have worked in the vibration analysis field, you probably have heard of my dad.

His name is John R. Hall

What does a wind based storm like a gale have in common with a monster bass amp? That bridge was destroyed by gale force winds.
Which leads me to surmise, that either 18er should plug his Ric directly into a gale, or...
Should play a suspension bridge instead of his Ric!!!!!!
