Best regards, Heinz

4 series ,each 1000 pcs ?
are you sure ?

Before you said:

"About "bass heavy" and "bass light" versions: I remember back that the original ~ 5000 pcs was shipped with a black bright box. This version - I'm sure - was produced with the target 25Hz f0. There was no additional changes at least during the first 5kpcs... Later I do not know clearly because of my leave from AKG. To repair of a K1000: As Karl wrote, a K1000 driver last for long time. However, the foam placed inside the center of the driver migh age... It..."

or

"Thank you for your inuts.
I know just, that the "first gen" was planned for 10k pcs. At least for these first series I guess that the frequency response should be much more linear."

And I think they started from 1000. The same way they did it with Akg k812. So I believe about 10000 pairs were made

OOUCH!!!!!

 

SORRY to all!

 

In my last replay about produced volumes per production lot I made a typo.

Instead 1000pcs it should be 10000pcs.

 

Another topic is, that I had a call with another colleage who left AKG much later than me, he said it was only 4 batches. This would mean 40000pcs in total.

 

But may be the company did later another batch - sorry I do not know.

Hello Heinz, I am big fan of the K1000. I was curious on how you prefer to setup the driver position for a listen? I spent a long time experimenting with the many different possibilities. At first, I thought I liked it the most when the drivers were the closest to the ear. Now I find that the sweet spot is around 3cm outwards. When the drivers are popped out all the way, the listening sessions can be a hit or miss depending on my mood and the quality of the recordings. I didn't like the K1000 when I tried them for the first time six years ago, but that was because I didn't realize I could adjust the temple pads in which, in my opinion, significantly changes the sound especially when the temple pads are fully plump. I find that my pair with the completely deflated temple pads sounds better with the drivers completely popped out compared to pairs with fully plump temple pads with the drivers also popped out completely. I think this has to do with a smaller gap between the head and the drivers which might create a more sealed acoustic chamber (more bass?) at least in the front regardless of the serial #. Anyway, my 3cm sweet spot seems to do the trick with any pair I try. Too bad that the most unique headphone ever created is still discontinued, it's hard to go back to any other ones.

Can we confirm that the serial numbers ran uninterrupted?  I see a lot of some numbers (4xxx, 7xxx, 10xxx, etc.) but little or none of others.

I'm guessing this will vary radically from user to user just based on each individual's HRTF- particularly with the K1000.

No wonder mine was in such a rough condition when I bought it (1030).

Hello Troymadison,

The questions you are rising are really important. I was always astonished why I did not read anything similar.

This is, because the effect you discribe is one of the rear disadvantages of the K1000 concept....

It has to do with the shape of the human outer ear in realtion to the fact that the K1000 membrane cannot offer a real flat wave front.

A simple explanaition:

If human are in the acoustic far field (which is true for almost all acoustic natural cases) the outer ear (and also the inner ear) is effecting the "incoming" sound always in the same way.

But this is not true if the sound is "entering" just a view cm in front of the ear entrance.

Basically I designed the acoustics of the K1000 membrane in that way, that when measured at 1.5cm from ear entrance, the acoustic measurements are in average (at many humans) the same as when the sound comes from far field.

However this is true for human average and may be not true for your specific ears.

That means for the K1000 listener:

Just experiment with adjustment of the driver panel relative to the angle to the ear. If you are satisfied with a specific angle the best would be to mark this position and use it in future also.

Sorry, I know this sounds not ideal, but as I said - this is one of the disadvantages of the concept...

Today I would know improved membrane shapes, but 25 years ago I did not have that possibilities with simulation technique.

Best regards,

Heinz Renner

Thank you - MKUBOTA1-  for this input.

What I described just before reading your post is exactly:

Reason #2: HRTFs

Thank you!

High,

About the design of the K1000:

You have to understand that the complete housing of the headphone and the driver itself is designed to show as less acoustic reflections as possible,

The result is of course:

> The sound like it is

> The "goofy" looking design.

;-)

Best regards,

Heinz
