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 want a very open neutral speaker try listening to the new monitor audio gold generation 5 or the Platinum generation 2. Those AMT tweeters are so sweet and the mid-range is very three-dimensional and open and the bass is tight fast and articulate.
@havocman

The hardness brightness in your mid-range is probably coming from the speaker cables in the interconnects.

Do you even know what he's using now? 

I have an LM-219IA that I run with Klipsch La Scalas. Exactly what you <don't> want - heavy and American, but they're an excellent match for my 24 wpc; they're 105 db. You could look for an equivalent over there. I've also heard the Devore's, an excellent suggestion, those really impressed me. 
Love my Living Voice from UK. Just upgraded to the highest ranked of the Auditorium line the OBX-RW4 with crossover outside in an extra box .... Just before they charge customs from UK to EU (Germany). With 94 dB they run easy with my 55 w/c SS amp and will with a lot less powered tube amp as well. They are quite small and lightweight and sound fantastic.
Hello,
What about a ProAc speaker. I heard a two channel floor stand speaker a few weeks ago. They have great mids. I would probably opt for a three channel with the ribbon tweeter. The other is Dali speakers. They have a speaker option for everyone. https://holmaudio.com/dali/
