Tiny little magnets, marked BECKER all over them ... in a DIY thread,
I'm not sure why wouldn't you just use the original driver in a JBL 4530?

And if not a JBL 4530 - they look like some of the older JBL wide range guitar speakers,
except the beckers look to have a much smaller magnet structure and stamped frame.

I know that one of your members has used its drivers in boxes of 4530, hence my questions. There are only very little information about these broadband, or if one of you has used it may be able to provide me with crucial information qt guy ...

Use LIMP (http://www.artalabs.hr/index.htm) to measure the parameters of the driver.

m not equipped to use this software, I do not have a microphone and I own a very basic computer!
In addition, a measurement is made attorneys in a box and not in free air.

I doubt anyone will have the information you seek. These are old relatively inexpensive speakers that probably don't have much of a following. Your best bet if you must find this information inexpensively is to to buy a Woofer Tester.

In the General Audio Discussions forum (here, on this website) there is a Technical References thread, and in this thread there is the famous Thiele paper, part 1 and 2.

There You can lean how to measure the parameters.
