$15,000 Floor-Standing Speaker Selection and Advice

@texasblues1959 because they would be the priced higher than local brands. Nothing wrong with them, it's just practical to chose items made in the area, less transportation costs. 

@iseland they are expensive and hard to place but ok

They are quite costly but in room that size they would really come alive. 

And in Europe you can easily find a pair for $15k US .

My 2 cents;

You can't just give a budget and room size and ask for loudspeaker suggestions. Well.....you can but good luck! 95% of the time the people who respond to such posts just recommend what they have. Silly. 

As others have said, you have to listen for yourself. 

Case in point is the recent Axpona exhibition of a $2M system featuring the reigning flavor-of-the-month Magico and their flagship monsters coupled with D'Agostino electronics. Today's version of the S'Phile website features a rave review of the sound. Check the 'net and various Youtube videos covering the show and some very experienced industry insiders, dealers, and experienced listeners could not get over how bad the sound was. The set-up was in a very large room but the Magico's arguably were still overpowering the room but here is the key-different people hear differently. Somebody else's gold may be your dog shite. 

One more thing-the very first response to your post recommended you get a huge subwoofer. News alert-going down to 20hz is not the be-all and end-all of good sound and it is not necessary for every listener. That is the hallmark, no offense, of not knowing much about this hobby. I recognize that false mental paradigm as my own when I was inexperienced at home audio. Almost 40 years ago I bought a pair of B&W 805's and falsely thought if I added a subwoofer I had all the frequencies covered and that was all I needed. Silly wabbit, trix is for kids!

Most people respond with the ones they chose. Understandably. 

For me a listening tour was necessary- and buying the ones I loved best at the best deal possible. 

I have Magnepan 3.7s, Bryston T-10 Actives, and love them both after much auditioning. They are used for different kinds of music therefore 2 pair.

Now I "need" a Wilson Watt Puppy 50th Anniversary speakers. And I'm looking for them used. Understandably. 

Get what you heard and loved. Then make sure your listening room matches the room you auditioned in. 

BTW my Cousin is a Sonus dealer (among other great brands). I get them at his cost (40-50% off retail) I had a pair- loved the craftsmanship and the snob appeal but the sound was dull to my ear.  Just me. I like French vanilla ice cream.  Maybe you like rum raisin. Make your own ears happy. Nobody's opinion who doesn't pay for your system matters. Only you happiness with your music matters.
