Best Speakers for Listening Bar I am building?

Hey, I thought this would be a good place to get some experienced input.

ANY IDEAS?

I am building an 1800 sq ft listening bar. The acoustic in the room will be fixed for minimum crowd noise and best hifi sound.  I don't have unlimited budget to work with,,,,but of course want the system to be something for people to come for. Bang for the buck ideas so far are 4 Klipsch La Scalas +subs. I am thinking that the vintage horns will throw a large dynamic soundstage and be kind of vintage fun. Idea 2 is more vintage as in refurbished Voice of the Theaters. Same kind of thing...but even bigger image and dynamics...and definitely a vintage fun thing to experience. Idea 3 is to just go modern BIG with 4 Tekton Moabs or maybe Encores. These are very large and throw a big image and can be quite dynamic..and these would be kind of giant speaker porn...but a good speaker. I don't have money for more exotic ultra expensive choices.                                   

All are very sensitive so tube amps will be used. 

The room is basically 50ft long x 36 deep.

Let me know...I have not heard Voice of the Theaters critically...so can't know, but seems good in theory
