As no one else has responded to your query (yet) here are my thoughts.

I’m sure a pair of CX50s will work with a Beomaster 1001, either as main or ambio speakers but I’m not sure how well. According to Tim Jarman, who should know a thing or two about older B&O, and ‘Peter‘ on this site, the amplifier in the Beomaster 1200/1001 has particular characteristics and performs best with the speakers it was designed to be used with - the Beovox 1200/1001. Tim, on the relevant page of his ‘Beocentral’ site, suggests another pair of 1001s for ambio use.

I’ve got a pair of white Beovox 1001s I bought with a non-working white Beogram 1500 as a project a couple of years ago but which I’ve not done anything about yet. I have to say I quite like their sound, and in some ways prefer it to the sound of my CX100s - but then my hearing isn’t what it was!

Thank you Cleve for your reply,

I was also pleasantly surprised by the sound of the Beovox 1001: warm, full, round with deep bass.
In my understanding the 1001s were entry level speakers designed to be primarily used as ambio with Beovox 1702, 1802 or 2702 as main.
But they're often found with second hand BM 1200 or 1001, so I believe they're also often used as main speakers (my case).

If I come across an other pair, I'll stick to them but they're not often seen around in white.

Please could you provide some links or direction on that:

I'd like to learn more about those matters.

What is your profile picture please? Is it a speaker or a TV ? I'm curious.

 

Thanks again and all the best.

 

Hi,

Here’s a link to the relevant piece on Tim Jarman’s Beocentral site

https://beocentral.com/beovox1200-1970s

As for my avatar, they are electrostatic loudspeakers, the Braun LE 2s. They are Dieter Rams’s reworking for of the original Quad electrostatic speakers the ESL 57, designed by Peter Walker in 1957. I had a pair of the original Quads 20 years or so ago and even today that are still capable of outstandingly accurate sound. I have always fancied a pair of the Braun LE2s to use with a white Beomaster 8000.

If you’re interested in a pair of white Beovox 1001s, PM me.

I didn't knew about the specific loudness on the BM1200, so I've learned something today, Thank you!
Anyway I found the whole system (I'm lucky to have a full set with matching Beocord 1200 and Beogram 3000) sounds great and warm.

I came across Dieter Ram's name twice today. Maybe I should have a look at his work.

Would be curious to hear those speakers sound! And they look great too.
