AKG K1000 - A collection of information and links

post #1 of 64
Thread Starter 
Here you find information, links to reviews, impressions, recommendations, and more for the AKG K1000 headphone.
I have been missing a central place for all this, so I decided to create one. Hope you find it useful.

Thanks to 'Richter Di' for his 'Everything about the K-1000 (K1000)' thread, which got me thinking about creating this thread.
The 'Other (non Head-Fi)' links are taken from this thread. Thanks!


History:
The K1000 were introduced in 1989/1990, and were in production until late 2005. Apparently they were discontinued because the machines used to produce them were worn out.
A total number of around 11,000 units were produced.

Description:
Quoted from AKG
  • Top-of-the-line, fully professional monitor headphones
  • Totally open design
  • Adjustable speakers for optimized personal sound
The K1000 are a unique design that is the equivalent of wearing a pair of loudspeakers on the head. The speaker capsule uses a unique, freely vibrating multilayer diaphragm driven by a newly developed, radially magnetized VLD (Ventilated Linear Dynamic) magnet system. Sitting in front of the ear, this dynamic transducer provides the best acoustic coverage factor. The earphones using no acoustically hard parts, the sound is absolutely free to develop in all its splendor. The speakers are acoustically finetuned in a computer-optimized process including time-energy distribution (Wigner distribution) measurements and made with advanced manufacturing techniques. The result is an unobstructed plane sound field in front of the ear that provides a personalized listening experience.


Technical specifications:
Code:
Type:Dynamic transducer w/VLD magnet
Sensitivity:74 dB SPL/mW (free field)
Frequency range:30 to 25,000 Hz
Rated impedance:120 ohms
THD: K2<=0.5% (200 Hz to 2 kHz)
 K2<=1% (100 to 200 Hz)
Max. input power:1000 mW, equivalent to approx. 100 dB
Cable:2.5 m (8 ft.)
Connector:4-pin XLR
Adapter:4-pin XLR to unterminated leads

Awesome work Kai ! If you need any help digging for info, let me know. Should be a great thread. I know that at this point I am truly enamored with mine.
post #6 of 64
Yes. Great idea!

When listening to mine, I wonder why I have other headphones. Only my speaker set up is preferred to them. And I haven't even hardwired them which actually makes a large improvement.

Tried to find the link to a DIY hardwire site but no luck

there's one thread that gathered all (most) K1000 info. i guess you should link that.
post #8 of 64
I was going to say, theres already a thread that does this, although it'll need a refresh.

I also find it unssurprising that you've used 4 posts where 1 would be a sufficiency.

Well, if you guys are pleased with the "Everything about the K-1000 (K1000)" thread then please use it.
I found it out-dated (summer 2007) and also lacking basic information though. So I decided to make a fresh one.

Duggeh. I find it much easier to maintain massive amount of text when they are split up in sections. Not having to deal with all the text for information, links, ... when I just want to add a picture. Hence why I reserved 4 posts.
You may of course prefer differently!

I think the following would be great, if you can find the info here or elsewhere.
Basically its production history.
* When was it released? ~1990 I think.
* When did it go out of production (first time)?
* When did the revive it? I am quite sure it was out of production, then revived a bit later.
* When did it go out of "final" production (so far )? Sometime 2005 I think.
* How many units were produced? Ever seen 8xxx, 9xxx models?
* The "mystery" behind the dark and light wooden boxes? When did they switch?
* Anything you can find..

That would be kind of you!

I have listened to this headphone and other expensive ones, it is not what you make it to be, you guys here listen to headphones from portables not real amplifiers evaluate headphones from a good amplifier and you'll see what I'm trying to say,there is no perfect headphone... you waste your money, buy a good amplifier and use good driver headphones from SONY and you'll never go back to those expensive lemons

I think that you may be wrong there.
