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?

Listen to davidbrinknyc- he's the one with the right idea.  Funktion One dominates the club business worldwide and QSC is a quality company building good sounding alternatives for less money.   
Ignore the Klipsch suggestions. And tbh F1 sucks at midrange. Martin Audio, L Acoustics, D&B Audioteknik, Danley… or just go with JBL.
You willing to step up to the plate?
I don't know how it would work with your budget....but...

Pretty much unobtanimum HOWEVER, if you can find them:  

Klipsch KP-600's

Two would probably do very nicely indoors (HAAHAHAHAHAHAHAHAHAHAHAHA  inhale, HAHAHAHAHAHAHA)

Four would be absurd.

(TWO would be absurd)

I once heard these indoors at the Klipsch listening room at their factory.  What was amazing is (and I am speaking VERY literally here) the hair follicles on my arms were feeling the pressure and though it was 'loud', it was nowhere near what they're capable of.

I recall actually looking at my arms and rubbing them from the vibrations.

Do a google search, salivate, and begin your quest.
