Does anyone has any experience with these speakers? How much is the used price for these.  Here it shows that they are from 1988-1991 era.

Fair, though very stylish! The Beolab 3000 is a lot better as the built in amplifier increases the bass which gives a flatter response. I have a pair in my hall. Mine cost £250 a few years ago - a bargain!

I use a pair every day in my office where they are well suited and yes, look very stylish! I paid ~300USD a few years back in good condition, not excellent.
