Help me identify speakers - AR90s? Value and replacement cost?

And I've never seen any in White. 

From the spatter spray on the back panel, I suspect that the white "finish" is a DIY job.

You can research sold prices @...

Thanks @kr4 , yes that would explain it and make sense.

Am I under powering these with the 55-60 wpc of the beolink passive? I've read they may sound even better with like 200 wpc?

Ugly! Time to get out the paint stripper! Yes they will sound better dynamically with more power. I would sell them and the B & O gear and buy new stuff like a streamer (Wiiim Pro) and powered speakers.

Based on the 3rd photo it seems the mid bass driver is showing signs of excessive wear of the surrounds, and I am guessing they all might be in need of servicing / replacing. Leave / sell them and purchase new (or preowned) when you settle into your next place. They, and the bigger brother, the AR9, were nice speakers back in the day, and I preferred listening to them with larger ss amplifiers. The speakers, room size, listening levels etc. always plays a significant determination as to how much power is needed. My best, MrD.

Thank you all, indeed seems best way to go is sell and buy new/used once settled. Appreciate the advice!

Switzerland might be too small to accomodate such large equipment.

You never know how much you can get for such old stuff.  For those speakers, I would say not much.  Looks like too much work to restore unless you are into that sort of thing.
