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?

Bag End as noted above is a great suggestion, their gear is robust, and will give what you require. I have no idea on their pricing these days though....Regardless, there are many ways to skin the cat. Have fun! 
Watch what you are doing, for yourself and your guests hearing loss is permanent. 

When I turned the PureAudioProject Trio15 Horn 1 speaker sideways (reviewed for Dagogo.com; see my system pics) I gave some people an idea. It's being used in some clubs now, suspended from ceiling. :) 



These speakers: http://www.theabsolutesound.com/articles/tested-cerwin-vega-cls-215-loudspeaker/ $1K/pair. I believe the current model is the XLS-215. I don't know where else one can get 110lb, full-range speakers with cast-aluminum woofer frames for anywhere near that price. 

...and this amp to drive them:https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F283614460903

Leaves you $1K for a good source component or preamp.



Look into HSU Research sub/satellite systems.

They are located in Anaheim.

The setup will be dependent upon the size of your listening area and don't be put off by the low price of the satellite speakers.
