Anyone able to tell the difference, in ABX of course, between the electrical signal and recording through condenser microphone from W18NX001 woofer? (the last 200Hz sine test)

Sensitivity is an easily measurable quantity, nothing magnetic in a condensor mic (most modern ones). I guarantee gooping a capsule will not improve it.
Definitely agreed. The D205TI's I replaced in the past were 2 inch dia and ffluid cooled.
But when I was getting materials for a line array setup, I purchased about 5 pieces of some tweet, don't remember what pedigree befor I committed to 200 units, so I've a few to waste in my feeble attempt.
Ed, thanks for the gum out hint, may try it. Was thinking heat on a flat exacto, and then bonding a blade to a handheld ultrasonic piezo stack feed horn. But was undecided as I couldn't be sure the hearing protection would protect my ears or that the acrylic goggles would prevent ultrasonic pass through from the eyes to my brain. No need to do a self imposed sonic attack thing.
He was so annoying, she on the other hand, wasn't.😉
Will do.

I guarantee this won’t work on Dan

Thanks.
I have good reasons to have doubts about my ability to understand things properly.
So I make questions or I ask for confirmation (like in a cockpit)

Sure. I'm commenting from subjective viewpoint using standard mixer/pre and headphones or speakers.
I think all the condensor mics I have dealt with run output coupling/matching transformer.
Consensor capsules and dynamic pickups improved, ditto output transformers.
I'm not winding you up Scott, with real sounds these changes are strongly evident, with sinewave excitation probably not.

Then Dan, a recording with/ without your goop would be a trivial thing for you to do from the line-out feed of the console, no?

If I may, the most beautiful acoustic guitar I had recorded in a studio was taken with three microphones. I think a dynamic and two electrostatics.
As they were not placed in the same places/distances, the phases are doing their own thing: just give them something to smoke ;-)
nb: The owner of the mastering/cutting room asked-me if he could add the mix of this tune to his demo disk in project.
I was proud as a porn star receiving an Oscar.
Damn I started reading that paper and found a new to me artist I need to investigate. George always ends up making me buy more music 🙂
Here are both.
The top is the normal diff drive. I have neglected to draw in the Ls/Rs, as we all know what is meant now by the circuit.
In the second one, the pickup coil is half the turns, so shows only half the dB/dt. So I double it at the summer, and subtract it from the vout. The net effect is the same, the output of the summer will be Rs of the drive coil. (was unable to easily find the greek symbol for summation in this version of visio..sigh)

Yes, or with my soundcard at home would be better....the experiments I ran were at work on the fly when the boss wasn't looking 😉.
To this end I bought one of these CM-H8C Large Diaphram True Condensor Microphone the other week.....same mic but different nameplate (Bock BK-1100C) from a pawnshop $25.00 but have not listened to it yet.

There are a bunch of AB loop recording experiments for me to run in the near future now that I am subjectively happy with the sounds of a range of 'goop' mixtures.
NYE experimental mixture was on a Jamaican DJ friend's decent DJ system in a marina large pub/beer garden venue running Reggae all night..... peace, love and happiness all round 😉.
When I have sets of formal test recordings (ie when I extract the digit) Scott's band filtered signal noise floor modulation analysis ought to be useful.
Previous critical listening to AB difference signal residual is informative and correlates with subjective impressions/findings....the difference signal sounds truly 'nasty' and weirdly/wrongly dynamic in nature.
Dan.
Ewrong again. Most modern codensers are fet amped not transformers. Did you reallt look inside any. And let AKG and Nuemann know about your goop, youll be rich. Not likely.
Yes, according to Neumann -
Ok so I didn't state 'true' condenser....if I meant electret I would have stated electret.
