What type of JBL stage monitor ?

[nrwjbl]

Hi folks,
I am searching for type of JBL speaker shown on pic attached.
Who knows exact type and years it was produced by JBL.
I was told this was a JBL product ? Is that true ?
Thanks a lot.

If the color is correct this is most probably a Stage Accompany design from the Netherlands, back in the day they used modified versions of JBL speaker units in their cabs.

They have a midrange cabinet design called SA4521 but it's loaded with 2x E110's and I've never seen one with a BiRadial.

Yes, you are right, this special blue colour stands for vintage Stage Accompany products from the Netherlands.
I think original (compression) drivers were replaced by biradial horn (like in 4435/4430 JBL monitor).
This box seems for me like a DIY version of an original stage monitor.

I think it's a DIY enclosure but maybe some JBL/SA freaks will know more
