Sound Stage and Imaging

Build a good kit. Some are excellent, and if you can type, you can build the kit. Obviously the whole concept is setup for best bang for the buck...the retail gravy train only has to make one stop.

These Falcon IMF 100 are well under 2 grand shipped. You will need stands. My nephew has them and they are a true bargain!

I’d stay on the lookout for some used Joseph Audio RM25s on hifishark, here, etc. as they’ll absolutely do what you’re looking for in spades and are well within your price target.  Best of luck.

For $2k you will not get hiend quality sound ,you may get a good older speaker but 

any speaker over $10+ years old the Xover the capacitors start drying out

then detail and soundstage diminish as the Xover starts getting old.

I have been upgrading Xovers for  over 20 years,and BTW ,most speakers 

even $$ expensive brands many put in average parts at best rated 7-9, which I have a Big problem with I always end up upgrading the resistors and capacitors , inductors only if low quality. Check out-  Humble homemade hifi capacitor test and see what your speakers have , resistors only 2-3 best MundorfUltra, or Path Audio ,then older Mills ,Ohmite gold . Ceramic , cement type are gritty and degrade purity of sound. Duelund cast are still the best rated around a 15  ,but Waay over priced and too big unless you have the $$ , there are others not far off for much less $$ 

Speakers are only part of the solution.  Better to find components that produce what you are looking for no matter what speaker you are using.
