Question Elac BS-312

[Photoro]

Hello,
Because I move allot I was looking for some small sized HIFI speakers which will be easy for portability, but as high fidelity as I can get. And the Elac BS312 seems to be the perfect speakers for me.
However the price tag is around 1800 euro and I can't find any comparison to other speakers so I could know how good they are.
Is it possible speakers of it's size to sound as good as the tech specs?
My dilemma is that they have 4 inch woofers who suppose to go as low as 42hz at -3db, but there are speakers 3 times the size who can't go as low.

If anyone heard this little speakers or have any knowledge about them please let me know if they are worth the hype.

You're going to have to have a very good amplifier to get the best out of them.

To keep the system portable I was planning to pair the speakers with a PS Audio Sprout 100.

I am just not shore if they are really that good as the specs say and the high price tag
