The bass impact and naturalness you are seeking call for a speaker system that does a good job of taking the room’s effects into account, otherwise the room will impose unacceptably large peaks and dips on the bass region. This is a problem inherent in small rooms, such as we have in our homes - the bass is much smoother in large rooms where concerts are held.
The dynamic contrast of a live performance calls for drivers that are just loafing along even on the peaks, so that the peaks are delivered without compression. This implies either prosound drivers (preferably studio-grade), or lots of conventional drivers.
Delivering the sense of being immersed in and enveloped by the acoustic space of the recording while still retaining good imaging calls for paying a lot of attention to the psychoacoustic implications of design choices, particularly those having to do with the radiation pattern.
And finally doing all of this without any harshness or listening fatigue or other audible coloration calls for paying attention to all potential sources of coloration, which are too numerous to list.
Doing all of this for five grand is a long shot. Doing most of this for five grand is possible.
