I need advice on which speaker

If you like transparent sound with excellent imaging, dynamic sound at all frequencies, defined bass down to 24 hz., with the all important midrange to die for.  They have 40 inches of ribbon drivers for the mids and highs, plus two 10" woofers (1 mid-woofer and 1 subwoofer) in each speaker.  Read the many reviews--the VMPS RM40 is your speaker if these sound qualities appeal to you.  If you can find a pair with the upgraded TRT caps and preferably built after 2005, you can find them around $2200-$3200, depending on the upgrades. These are large speakers and they make effortless music.  They are also adjustable to any room--yours would be awesome.  There are pots on the rear to adjust mids and highs in very small increments.  The bass can be adjusted to sound about any way you'd prefer from very tight and punchy to more rounded and full.  They are 240 lbs. (66" ht.) each--260 lbs. each if you find the BCSE full blown edition Brian Cheney made.  The VMPS speakers are no longer being made since his passing, but there are many helpful people on Audio Circle--VMPS that can assist with any potential problems.  The standard VMPS speaker went for about $4500 new.  The BCSE edition went for nearly $8000.  No matter what other ancillary equipment you surround it with, the RM40s are more than up to it.  They sound fantastic with any type of music.  After buying a pair of the lowest cost speakers Brian made, I was so blown away I asked him if I could demonstrate his speakers in my own house.  I did so for the final 5 years of his life.  No one gives you more speaker for the money than VMPS.

With the HINT (I have one), in that price range, I really liked it paired with the PMC Twenty.24

thanks everyone, indeed it is a lot of choices... it’s going to take some work to find a pair that meets my need....
Oh yeah I have considered bookshelf speakers too

I like chrshanl37s’ approach. Best way to learn what one truly prefers regarding sonics of ones’ system.  However not so easy to buy/sell large speakers, given shipping concerns.

A shout out for Thiel CS 2.7- you have the prefect space for this speaker.
