Looking for a speaker for my LM 845 Premium


Today I have the Tekton Double Impact, but now matter what I match them with there are some hardness / brightness in the mid range.
I am looking for a high efficiency speaker for my 30W tube amp.
sensitivity > 92db
impedance min. at any frequency 4 ohm.
My room 25m2

And if possible made in Europe, Why? because import from the US add 1/3 on top of the price, and more if it’s a very heavy speaker.

If you can afford them, Avatngarde Zeros would be a wonderful match.  They are a pain to setup but are amazing once they get dialed in.  They are not as bright as a lot of horns and will do well with a less warm 845 based amp.  
LM amps are magic and despite their low output wattage, don’t need super sensitive speakers. I have a 508ia driving Peak Consult Princess IV Signatures through Auditorium A23 cabling. For what I listen to in my modest 11x17 foot room (jazz, classical mostly), it is a special combination.

Martin- Is the UK a problem on VAT?
If not I would look at Spendor, Tannoy
Stirling, and I am sure a multitude of others.

Avoid anything called a monitor.

Best,
There is no reason not to buy a used speaker.
if you just go for a speaker that is pretty flat 8 ohms. Focal are nice. What is your budget?
