Hi and welcome to Beoworld!
Are you talking about the 1985 stereo radio-cassette system versus the 2020 Bluetooth speaker ? They have next to nothing in common and nothing at all in term of sound.
First, the Beosystem 10 is more or less a Japan production that, how to say this, has only the B&O look. It' two wide range speakers sounds flat, very average and of course, old, absolutely not B&O. But it is still a very nice device on display who needs regularly to have the dust removed from its shinny black panels.
The Beolit 20 is a portable BT speaker with tweeters and woofers and has a more deep, detailed and modern sound.
Their footprint is also slightly different. The BS10 may be wider than your Tivoli system but also thinner and can be hanged to the wall.
Prices may also be very different.
Depending on your budget, your needs and the way you have to organise your space you may want to consider:
- a Beosound Century: it's very wide but can be wall mounted and color panels for the speakers can help to make it more discrete. Can be remote controlled.
- A Beolit 12, same as Beolit 20 but they're cheaper, Airplay not BT and its less boom sounding than the 15/17/20. The 12 can be remote controlled.
- If you can place the speakers away any Beosound Ouverture/2300/3000/3200 will give you a small footprint. The Ouverture has a tape deck. Can be remote controlled.
All have aux-in.
Hope this helps.
