Types of speakers to create nightclub style sound?


Admittedly, this may come off as an unsophisticated post for audiophiles, but I'm seeking advice nonetheless. 

I have a house with an open floorplan and love entertaining. I'm looking to create the auditory feeling of a high-end nightclub at home, as opposed to having a setup with the goal of creating a single ideal listening point. After traveling to Ibiza and hearing some of the world's best nightclub sound systems I fell in love with how they bathe you in sound. Since I can't fit a Funktion One Dance Stack in my home, I'm curious as to what I should look for in the home audio realm to recreate that feeling of filling a room with powerful sound that isn't super directional. 

With a total initial budget of about 4-6k (1k - 3k for a pair of speakers), what qualities should I begin looking for to create this sort of system? I'm thinking used higher-end speakers might be a better solution. 

I've noticed a few different categories of sorts: some speakers have a single driver with a wide-range, like the Zu Audio Soul, while others have several for different drivers, like B&W 603. I absolutely loved the line-source sound from Martin Logan ESL speakers, but their directionality is exactly the opposite of what I want. Moving 2 feet to the left or right of their line of fire made it sound like the music was coming from the next room over. I live in Los Angeles, so there are plenty of used, good quality, higher-end speakers circulating in the marketplace. Can anybody offer a little guidance to narrow my search for what sort of speakers/amp combination might best accomplish this?

Thanks for all the info. I know the setup might be overkill (Martin 2x X15 + 2x x115 + amp + DSP) for a open space of 28m2. I guess I will be always at 50% of the capacity of these speakers. However I also plan taking them to beach houses and other places where I will be able to push them higher outside. No need to rent anymore.

I will check the Tannoy setup! If can get the same sound quality for cheaper why not
Cerwin Vega towers and add one of their earthquake folded horn woofers.


  QSC speakers and a subwoofer.

 Lots of brands you can work with. 
No QSC. Used and heard on a few occasions. They sound like crap. Jesus, who in their right mind and not deaf would recommend QCS? 


I saw the cerwin vega, they look great but difficult to find in France.

All Uk/french brands are easier to access (Funktion, void, l acoustic, martins). But for the budget Martins seems like the only high end accessible.
 Then the solution is obvious.  Martin audio which you have already found or if you need to be on a smaller budget, used Tannoys.
