I have them and while they are very nice they are not flawless. Their strength is the very nicely behaved midrange and treble. It's reminiscent of the treble-recessed Sennheiser HD650, while still retaining good clarity. Their biggest flaw is the bloated sub bass and weak mid bass. They don't...

I own a good measurement mic that I use for work. It's an Earthworks M30 . I also have access to a B&K 4006. I was looking into getting a IEC711 coupler to measure and EQ my in-ears. But unless it's a B&K or Gras it will most likely come with a cheap element and without a calibration file. I...

Thanks for the tip Ferbose. I tried it and found that my experience mostly agrees with yours. In my setup I use a set of active nearfield studio monitors- the JBL LSR-25P, a matching LSR12P subwoofer and my K-1000 driven by a B&K amp through two Rane TF-4 step up transformers. The monitors sit...

I'm 40 and my hearing is still good to about 18k, albeit at elevated levels. 16k is fine at any level. I used a function generator and my K-1000 head speakers to quickly estimate my hearing ability last week. I fired up the NCH tone generator from http://www.nch.com.au/tonegen/ and stepped...

Just wanted to share this with those who own or consider buying the AKG K-1000 head speakers. I work for a large AVL (audio video lighting) systems integrations company. I get notifications of pretty much all new pro audio products. Last year Rane came out with a high-end, class-D, 4-channel...

Thanks again Joe. You rock! I ran some sims in my loudspeaker software. The big impedance 200 Ohm swell is no problem. A zobel takes care of it easilly with fairly small cap values.

I trust your expertise. If you have a minute and don't mind testing them again maybe you can see how good the matching of the transducers is? I'll take a 500 point zma file then. Thanks.

You know, I just used the SPL trace program from FRD Consortium and got a vey good .zma that I can use in my lspCAD program. So, no real need to email me the results. But, seeing how high the impedance peaks and how it never really gets below 135 Ohm, maybe a confirmation of the results would...

thanks for your interest in the subject. I do have something cooking and hopefully will show it soon. I do have a way of measuring impedance (software and a pro card), but my jig is not ready yet. I guess it's time to actually solder it up. Yes, I want to make a passive circuit and need the...

Has anyone measured the impedance of the K1000 over the full spectrum? If yes, would you mind sharing the graph or the .txt .zma or whatever format your measurement rig outputs? Thanks

Hi, my first post in this forum. I posted this at Headwize.com but I thought I might get a few more comments here. I recently bought the AKG K-1000 headphones, and while these are a well known entity with many reviews on the web and in press, I haven't seen the approach I'm about to describe...
