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
http://www.bang-olufsen.com/product-archive?ProductName=BeoVox%205702
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!

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.

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.

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.

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.

Hello all B&O vintage fans!

I am fascinated by the B&O vintage products and I collect them since more than 30 years. During a trip in Denmark to visit the B&O Museum in Struer, I found, in Ringsted, a pair of these beautiful speakers with their stands. They were used at "Danmarks Radio" during the late 70's early 80's.

Their size is identical to that of the Beovox 5700 with an extra black box underneath which contains a professionnal amplifier fitted with xlr sockets. A protection circuitry allows the speakers to be connected with more powerful external amplifiers.

In front of, a small red light indicates that it is on. I would estimate the power, in comparaison to other B&O amplifiers and Beovox 5700, at a good 75 - 100W.

The midrange dome and the tweeter are the same than those of a 5700 but the boomer is a 31 cm (12").

Subjectively speaking, their sound is different enough than the Beovox 5700. It is more natural and less "hifi", like if you switch off a loudness.
The frequency response seems to be very linear; for example all the notes of a grand piano seem to have the same level without these unpleasant resonances that is the defect of many speakers.
I only have a few photos because my son found them so good that he took them away to his new apartment for mixing all his recordings (He plays music in a rock / hip-hop band).

I have planned to make a detailed review of these Studiomonitors with plenty of new photos during a next visit at my son, who lives in Nancy nowadays then this will be after Christmas... See you soon!
