Where in Europe are you? I can make some general reference to the UK, if that helps. Pretty much anything available in the UK is available in the EU.
This forum might be of more help as it is the largest AV forum in the UK -

Your budget is £360 to about £1450/pr.
Can you tell us the size of your room? Big room = Big Speakers, not so big room = not so big speakers.
Am I right, this will be part of a Surround Sound system?
I would start with
Dali Ikon 6, a highly rated speaker, for a modest
£999/pr -

Getting into a pretty big speaker, and pushing your budget right to the limit, would be the
Dali Ikon 7 at £1460/pr -

The
Monitor Audio SIlver 6 (£1000/pr) and
Silver 8 (£1250/pr) are certainly worth considering -

The largest selling brand of speakers in the EU, or so I have been told, is
CANTON from Germany. Well worth checking into.

I'm using
Kent Home Cinema as an example, but you should be able to find better prices in the EU.
Canton Chrono 509.2 DC Floorstanding speaker (£1399/pr) -

The new
B&W 683-S2 (£1150/pr) sound pretty good, a bit soft in the bass, but the -6db rating is 30hz.

On the lower end, the
Wharfedale Speakers are very high value, I have the older
Diamond 9.6 floorstanding speakers, though I got them for a steal.
Wharfedale Diamond 240 (2x6.5"/165mm), £699/pr -

This may be unique to the UK, but the once £1000/pr
Tannoy DC6T-SE are now in the
£500/pr to £600/pr price range, and are very impressive speakers for that modest amount of money.

Also, very popular since its introduction, the
Dali Zensor 7 at £730/pr are certainly worth considering.

As to bass specs, while it is certainly ideal to get 30hz at -3db, those speakers are few and far between. Most better speakers concentrated on clarity and smooth balanced bass rather than deeper or more intense bass.
To get from the -3db spec to the
best guess -6db spec, you can subtract about 5hz to 8hz, and you will have a fair guess.
So the Dali Ikon 6 are rated at 37hz at -3db, that means the -6db is going to be in the 29hz to 32hz range. That's pretty decent. Those speakers should do well for both music and movies.
The
Wharfedale Diamond 240, according the the Wharfedale Website, are rated at 40hz at -3db and about 35hz at -6db. Establishing that my best guess 5hz to 8hz is a pretty close guess.

Just for reference, the
Diamond 250 with twin 8"/200mm bass drivers each, are rated 35hz at -3db and 32hz at -6db.

The spec for -6db is still very usable sound. One could consider the -3db virtually flat, and the -6db down just a trace. Again, -6db is still very usable sound.
Lastly, don't confuse Perceived bass with Rated bass.
Deeper bass does not mean louder bass, and louder bass does not mean deeper bass.
There are many speakers that have modest bass rating, yet the bass response is bumped up to make it seem louder, which people assume means deeper. Equally there are speakers with very balanced bass that go exceptionally deep. Don't confuse the two, Deeper Does Not Mean Louder.
My system is something of the perfect example of this. I have 12" 3-way DIY box speakers, that are rated at about 40hz. My other speakers are rated at 28hz at -6db with twin 8"/200mm bass drivers each. For movies, I kick in the 12" speakers, and even though the bass isn't as deep, they add tremendous impact to movie sound tracks. But the impact comes not from deeper bass but from moving substantially more air. There is more impact from being hit with a wall of air as opposed to a puff of air. With both speakers on, I've felt my hair ruffle and my clothing move from bass impact.
While Subwoofers do go deep, the real advantage is that they are very large and move tons of air creating very substantial physical impact.
So, while you definitely want response close to 30hz, don't get too hung up on a few Hertz one way or the other.
Hopefully that has been of some help.
