Source for FRD and ZMA files?

[Nvr2manybikes]

Hi;
Does anyone know a good source for .FRD and .ZMA files for drivers (to use in f4ier's Crossover simulation program)?
I know some would say - just measure your own - I will do that once purchased but I would like to do some initial sizings to get in the ballpark before purchasing drivers.
There were several threads out there from people who were starting pages for catalogs of such files, but several were dead links and one was in french.
Any good sources?
Thanks

Have you tried Googling 'zma frd files'? I did.

Driver FRD & ZMA files

Also PM wolfteeth. He's got some as well.

A BIG CAVEAT! All of the files you find on the www were created by the originator's own testing methods. The most accurate files of this type are those obtained using a standard test baffle. If they were obtained using a home cooked speaker box of some sort, they may not be suitable for modeling.

Thanks Doctor! (boy I feel like I left the Amp unplugged)

Wolf, thank you SOOOO much for posting that zip. I've been looking for a few of those FRD/ZMA files forever.

I just stumbled across this thread as I was looking for the same thing. Thanks for posting that excellent zip file Wolf!

Do you still have these files?

 

[wolf_teeth]

It was not my box account, but i do have the zip file. Ping me your e and we'll see if it's small enough to send. Not certain as I have not looked at it in a while. That was created in 2011.

No worries. I downloaded VirtuixCAD and another tracer program since then, so I can do this as long as I have a clear source of the charts (mostly PCD files). Thank you for your help, though!

The second best way is to learn the tracer functions in various apps and do them yourself.

There are many files here, which I have had for many years, and others are made by me, they are all in one place, there are also crosses from various drivers, I hope it helps those who do not have access to measuring tools.in the same folder there are Klang&Ton Hobby-Hifi speaker construction and Construire Italy, enjoy!

Thanks for all these issues! Such a strange thing that Germany has two speaker magazines going strong all this time.

And the younger magazine was established by the former employee of the older one. After you learn the ways of business, then you become their biggest competition, as usual.

which one of them?

 

[markbakk]

K&T is the older one.

They also seem to have a new youtube channel (with english closed captions)

Who wants to make their own ZMA or TXT files, here is a good tutorial on how to build a jig, I made one from parts recovered from amplifiers, and I had the box from an android box, I also have DATS V3 but with the jig I make better measurements with different programs, Arta/Limp, Rew, Simpes. here are pictures of my jig. Here is a link how to build a jig yourself: https://midwestaudio.club/resources/easyzma/

Hey guys, does anyone know how to get hold of Hobbyhifi 04/13?

I tried to email bestellung@hobbyhifi.de but the email bounced.

I don't want to spoil the mood, but for various reasons the use of FRD and ZMA files from other sources is only good for checking whether a project seems promising.

When it comes to the development of a crossover, you actually have to make your own measurements of the drivers in the intended cabinet.

But maybe that was already clear to you anyway?

Many greetings,
Michael
