But you have no idea how good it feels to slide a sharp knife through a speaker cone.

Oh, but I do. As a kid, I punched numerous holes in the exposed TV speaker with my Dad's pointed meter probe. The dry popping sound was just exquisite. I can still remember it.

Very interesting.
How did you manage to keep cone mass the same after the surgery, maintaining the same sensitivity?

Is it possible to make an audio recording demo like here:

Very interesting.

I'd love to see the same done on a Aurasound NS6-255-8a. I only have four, so wouldn't want to risk it myself.

What would happen if you just did beads of thick super glue and not cut the paper?

underwhelmed.

this comment is underwhelming. what does this statement contribute, except to make you look like a jerk. this is exactly what is wrong with this board. a few years ago you would never have seen a reply like this.

Don't rag on him so hard! He turned a sow's ear into a pierced sow's ear.;)

Too right, Ricky; the sound went from awful to sorta tolerable. The point is to work up the courage to attack more expensive drivers.

Cool experiment. Would like to see before/after distortion plots too if you got 'em. Though I read somewhere painting white dots on the cone will lift a veil as well....:D

THD zoomed in. Blue is after.



I could try white paint, but black paint had no effect, so it's doubtful.

So I gather from all this that paper cone cut up is preferable to paper cone break up.:rolleyes: I would say the downside is having a destroyed cone.

Maybe I can convince you to see it in a different light.

How is the cone destroyed if its still making music with less breakup and improved response in the pass band?

The net result is very impressive. The primary break-up is reduced by 11dB, distortions of all orders are lowered, and subjective sound quality is much improved.

In other words, there is no downside, unless you like the sound of paper cone break-up.

Very cool experiment
