Help identifying 70s speakers

[Sunforest]

Hi, I recently purchased a pair of german speakers (30/35 Watt 4 Ohm 2 Weg) and I have one emblem but the other is missing. Trying to identify the brand if possible. Pictures attached. Any info would be great but I am guessing these are just unbranded speakers. Thanks in advance!

Update... I have had a response below on previous thread in wrong category but rather wait if anyone identifies before attempting this...
if you can remove the grille and get a look at the drivers, that sometimes helps. If you can (carefully) remove the drivers, post the numbers stamped on the backs and that may help identify them.

Braun?

Doing some quick googling I found this picture with a matching emblem as on the back of your speakers there, kirksaeter made some very good speakers, but I was unable to find a similar speakers on google images, looks like they could be promising though, keep us posted

I got a chance to do a little more research and it looks like that "hifi din45500" logo is on a lot of German made speakers.

This link explains more of what those markings mean. I believe I was wrong on them possibly being kirksaeter, it just looks like a lot of kirksaeter adhered to the logo and what it represents. It basically states the speakers have been quality checked to be within 3db of each other from the ranges of 250hz to 8khz.

My first reaction to the picture was Braun also.
