What makes a headphone "fast"

[NightStalker]

Well I just got slightly out classed

Its the thought that counts aint it

I agree. A very fast headphone can sound murky, bloated, and undetailed when not properly driven. This is due to the drivers just not getting enough power or signal strength from the source/amp.

What if we took a strong magnet and placed it on the back of another magnet? Adding a stronger magnetic field to a good sounding driver. Maybe this could help the speed and make the driver a little faster.

I'd be very surprised if that would actually work and if it does - without influencing all sound characteristics of a certain headphone. Somehow I believe that it can't be done without a lot of knowledge on how dynamic drivers work.
I think damping or modding the headphone chassis might yield quicker and more controllable results.

Ahh yes, the old "Crap in, crap out", it's amazing how so many discussions come back to this phase. Personally, I think we overlook this too much.

And gsferrari, I read your Theory, yeah. I also noticed you used a lot of big words, good job. It was a little long, so I didn't read it, but I gave you an A anyways

Ive seen it done before but i didnt realize what they were doing till i read this post and put it all together. It could be a simple mod that would probobly have to be tested by listening to to hear if anything changes.

I have tried to remove the second magnet but it is glued on with epoxy or somthing and i figure if i tried to force it the first magnet may pop loose and then the whole driver would be ruined.

"Crap in, Crap out" for life!


HOW'S THAT FOR A POMO POST!

Inertia is determined by the mass of the moving parts. The heavier they are the more inertia they have and the slower they'll start & stop moving.

What you want for a fast driver is the smallest moving mass and as much force driving that mass as possible. There are various ways to do this, such as using neodymium magnets, lighter aluminum instead of copper in the voice coils, using superlight diaphragm materials, or getting rid of voice coils & magnets altogether and going with electrostatic designs.

Is that from the movie Orange County?

I've done a bit in sub design so I think I'm actually qualified to talk about this item. The drivers all move at the same speed of course, but the damping is generally the biggest factor.

So whats the difference between good damping and bad damping? Is it like motorcycle suspension? I.e. You want a progressive increase in damping/spring rate so that the suspension responds quickly to small changes, and larger changes are prevented the nearer it gets to full compression.
If so then the perfect damping would be one that is variable under load, that allows as much movement as possible except near the end of driver excursion, which would blur the sound, primarily the bass.

From my reasoning :-


Excessive Damping - slower attack speed and faster decay speed
Insufficient Dampint - faster attack speed and slower decay speed
Correct Damping - fast attack and decay speeds without overshooting

Listening to headphones sounds very dangerous with your descriptions

Attack speed, I don't want to be attaked by my cans lol...ok bad joke

Whats dangerous about the effects of damping ??
