That's an interesting find! Nice to see them used for pretty much their original purpose as well 🤒

All those stickers might be interesting to see. The amps might even be DR's own design, small series stuff like that was sometimes built in-house at broadcasting companies back in those days. I suppose there's a trimmer for level calibration behind that "styrke" label, as it seems one of the screws has been sealed.

That loks very interesting, would love to have those in my studio! The 12" bass drivers looks like SEAS with rubber membrane and your son is owning a Beomaster 2000 in rosewood, is he using it to drive (Yamaha?) monitors? Nicely equipped studio, though it looks like it could need a reel-to-reel recorder 🙂

Being a student, I only use a Zoom R16 recorder into a computer with cubase 5 standard with some extra VST's, mintoring through my MS150.2's.

I agree, very nice find.

B&O produced a couple of different speakers specifically (or modified) for Danmarks Radio.
Definitely collectable !

I found type 6257 mentioned as Beovox 5702 here

Yes Mika, the "styrke" label hides a trimmer for level calibration.
The amplifier is really a professional manufacture and doesn't seem to be designed by B&O... 😁
I won't forget to take a pic inside when I will go to see my son, the lucky user of these beautiful machines.

Yes he uses a good Beomaster 2000 with his Yamaha NS10M. He took me for their connexion my dear Monster Cables M1 MKII  ❓ because he found that this setup gives a sound very sharp and precise in particular for the quality of the voices. 
The NS10M are a famous standard in many recording studios and his are finished in Indian apple tree...
He only has a Beocord 1600 reel to reel and uses it sometimes for the fun.
He uses Samplitude and ProTools if I remember well.

Note that they are different from the GB Beovox 5702 (Type 6251).

I am almost sure, that you will find the amplifier to be a homemade type rather than a B&O.
Could be fun to look inside.

These particular speakers were listed for sale several times.
Happy to know that they ended up by you.

Hi Martin,

Of course I won't forget to take a photo of the inside!
What I remember is that it doesn't look like a B&O manufacture.
The electronic board is made of epoxy glass, the tracks are thick and tin-plated, not as fragile as B&O where, when you remove a component if you doesn't take great great care you remove the copper track with!... 😕
Almost all the components are of professional grade and this amplifier seems to be designed to last centuries!
