Real world Loudspeakers what does very good cost ?

Legacy Audio makes the Focus SE and Focus XD, depending on your amplifier they are well regarded. The XD has an internal amp so mates well with tubes, if you have a bigger SS amp then the Focus SE’s will work well. $11,900 for SE and $14,172 for XD.

Soix very true ,a nice used speaker can be good ,I did this with a older Dynaudio 

and totally upgraded the Xover ,which is the ❤️ or the 🧠 of the Loudspeaker .

the vast majority has a average or below Xover in quality , thestock Xover was maybe $250 in parts I spent $1500 the speaker is night and day better sounding .

I am always looking for a hidden gem . I heard the Marten Oscar Trio I thought very good under $14k very musical . I guess most speakers will have compromises 

matching your electronics too is equally important .

$400 for Elac 6.2

$1100 Human Speakers DK 1

$1700 Wharfedale Lintons

$2000 Polk r700

$3000 Q Acoustics Concept 50

$5000 Klipsch Forte IV

@soix  if I lived in the USA I would buy those speakers as they look like a great buy.

I've found audio expos to be a good place to hear many speakers and speaker types at once.  No matter the upstream components, or the room setup, you should be able to get a feel for types -- e.g., box speakers, open baffles, panels, horns etc. and then brands, to further explore.  Also, because of the number of speakers at a show, the dollar question can be more easily explored.
