Speakers for a Large Room (20’x37’)

@cissado, thanks for your info, especially since your space is similar.  I'll check out the Paradigms.  We're still in the process of getting some rugs down so there's a lot of echo right now.  

@jackd  Hadn't really considered a boxless speaker.  Are there advantages over other types of speakers in a larger room?

@yyzsantabarbara , why would the Blades be a better choice than Cornwalls?  Does the width of the baffle have any influence in terms of pressurizing a large room?

Thanks so much for all the great info.  This gives me a lot to think about.  I am fascinated by the Vivid's looks and described performance, and will be keeping my eyes and ears open for a chance to hear them.  The Klipsch Jubilee's are also of interest, as are the Cornwalls.  Any other thoughts, don't hesitate to post.  Thanks again.

To answer a couple of questions, my ceiling is 10', and I listen mostly at low to moderate volume levels.  The need for a speaker that plays really loudly is low priority.  
@islandmandan You say your Tannoys are custom but I wonder if you could equate them to the Ardens,or perhaps a larger model.

@yyzsantabarbara  Thanks for the pointer to the Yamaha NS5000.  I'll do some research.

I'm sorry @danager  but I missed seeing which speakers you were referring to.

@fiesta75 Thanks for the reference to the JBL Everest.  Lots os folks thought it was the bestof show at the recent CAF.

Thanks for the Tannoy/Cornwall comparison @sbrogdon , I appreciate it, as this is germane to the direction I've been considering.  Not to say I won't research all the other speakers mentioned.  

@tomic601 Curious to hear about how you tamed your room.  I'm currently using a Lumin U1 Mini into PS Audio DSJr. into Backert Rhumba pre-, into Pass XA30.8 into Vandersteen Treo CT's in the subjeft listening space.  I use Qobuz through Roon and have an AudioLab CD player, though I hardly ever use it.  I've just moved the Treo's into the room, and don't yet have a rug to tie the room together :)  I'm thinking the Treo's may work, but am here trying to find another solution in case they don't.

@sbank I'll probably use the 30.8 during the colder months and then switch to Belles Aria separates when it gets hot here in the Southeast.  My tube amps are all low power (<10wpc).  Then there's always Class D.  Which Tannoys would you recommend for my space?

Who is the Nola dealer in the U.S.?   These look interesting.

Thanks for all the suggestions guys.  As @tomic601 says, I just need to get out there and listen.  At least now I have a manageable set to evaluate.

Humans are ok.
