Can someone help identify this driver?

one day....
When i was a kid i played in a Blues/Southern Rock band with my dad called Word Of Mouth (they Didn't know any better! Imagine my shame when i discovered Jaco!) it later became a Southern Rock Metal band (somehow) he still plays in to this day.

Well back when i was part of it, we had a real mountain man guitarist, a rattlesnake chewing, 6'-4" rawhyde boots on hardwood floors kind of frontman named Dennis Calhoun, well he up an bought a north carolina mountain one day and split.

One of the things he left behind was his signature home build effect, a Talk box.
Not one of those wimpy Framtonesque (huh, spellcheck says Framtonesque is a word!) lightweight Heil jobs, but a 50 watt Music Man amp running to a massive driver mounted under a mic stand, which he then bit a hole out of and attached a half inch copper pipe that went in your mouth, then into a SM57 which was then plugged into ANOTHER MM amp wired to a marshal half stack.
Anyone that has tried a Heil with a bass knows its too thin to do anything, IMO its too thin for guitar, but that monster was so loud and deep, you controlled the sound no just with your mouth, but with your lungs and stomach! Crazy sound pushed out of it.

Sometimes this setup would have the polarity wrong, or something wasnt grounded, sparks would shoot between his teeth and the show would go on. Pretty rock and roll. Ge had hands so rough (carpenter) that he would use them like a violin bow on his guitar, Chuga-Chuga-like sandpaper rough, never heard anyone else make a sound like that from a guitar. His hands were like a surfers foot.

I came across a pic of the original prototype of "The Bag", Kustom's talk box, that was to be worn around like a purse apparently. They didnt catch on...even with the fringe.
Maybe because they used a teeny little driver like Heil did too.

So this driver looks exactly Like the one Dennis made, Any Idea what it is?
I have failed in recreating this.
Also, what is that huge capacitor?






Careful, from across the room, this pic might look a little...nsfw...

A similar thing happened to me, on youtube under REDSEEDLESSLIVE if thats still up is a video where I get electrocuted thru the mic, killed a tooth. It was heavy amp current too, I touched the bass to the mic to explain why I was so shook up and couldn't sing, the g string welded itself to the tuner and lit up bright orange and sagged. What causes that? Am I right polarity>? or something else?
 
The cap is a first order high pass filter, the driver looks like an EV 1823m (will need to check the number, memory a bit foggy) with a custom waveguide/flair to a mouthpiece. Without the cap, the diaphragm will not hold up due to over excursion.

Years and years ago I built a Talk Box. It consisted of a large EV horn driver coupled to a plastic tube. A capacitor limited low frequency content. My lady wife bought a Denim handbag and sewed it to allow for the tube to exit. The player would sling the bag around his neck and the tube in his mouth. A foot switch swapped between the amps speakers and the talk box. Worked very well. :D
 
... the g string welded itself to the tuner and lit up bright orange and sagged. What causes that?
a bad bit of wiring inside an amp, combined with bad electrical supply from the house. Afaik one or the other shouldn't kill you, but often fools deliberately knobble the house ground at the amp to "fix" ground loop noise, banking on the amp wiring being good. Then you get the odd "accidental" death and welded string.

This was at a poorly put together festival, miles of thick 2" electrical cables, it was starting to rain, the lights shorted out too.
something like 10 power amps in the PA, would PA wattage contribute to the crazy amps?
I also had my bass grounded to kill a buzz, that might not be safe, but my sure fire way to kill lift noise is to alligator clip a wire to the bridge and then tuck it in my pants. sounds stupid when I say it out loud,,,,

you mean the PA wasn't grounded!?
It could have killed me, let me see if i can find the vid.
Since the lights had just gone out it is very cool looking.
I still haven't fixed the tooth, have to get to the dentist. if it wasn't so ugly i'd post a pic of that too.

This is right after my electrocution

 
I waas wondering if something like this would make a talkbox usable with a bass

That might be a cheap one, maybe not what i'm talking about, I was reading about these things, i'm not talking about an eq boost, these things supposedly add bass with some kind of digital processing.
I was originally thinking an octave, but don't those need a staccato nato to work? been I long time since I tried one. I know they don't track chords..


By the Way my step dad only uses Mesa tuba amps, he has an old Boogie, and 2 modern ones (the kind Trey Anastasio was using in the 2000's not sure of the model). And Mesa cabinets, I think he has a 2 12 and a 4 10, again i'm not sure, its like stack and a half high..


WAIT, my Stepdad has en Eventide Harmonizer, THAT plus the driver signal should do it... YEA>? I'm thinking a thicker hose, and powering the driver with a guild 15 watt head thats laying around.

A talkbox like this is cool, clenching your diaphram, or squeezing your stomach makes boomy crazy sounds. Too high tho. Sounds amazing with harmonics. The air and vibration blasts out til you worry about organ damage.

thanks again for sharing years of knowledge.

I think this is it

ABSTRACT
A deep bass sound booster device comprises a high-pass filter to which an input sound signal is fed and which permits only a frequency component higher than a predetermined frequency to pass through so as to output a resulting signal, a bass booster to which the input sound signal is fed and which amplifies only a frequency component lower than the predetermined frequency and attenuates another frequency component so as to output a resulting signal, a switch to which the signal output from the bass booster is fed at one end and which, when turned on, outputs that signal at another end, and an adder to which the signal output from the high-pass filter is fed and to which the signal output from the switch is fed, the adder adding together those two signals and outputting a resulting signal.

looks like the patent expired too!
