Speaker Help Please: Floorstanders around $1Ok to fill very large space with no sub

Sorry, didn't notice the $10K range.  I thought older mbls would be reasonably priced, but afraid I haven't been looking at the marketplace. I like the mention of the Ohm speakers, if you want something that doesn't require sitting in a sweet spot. 

If the object is to fill a large room with no subs, as it was for me, Legacys do the trick. Not the last word in refinement, but they do extend the bass. Tektons are another plausible choice for full-range floorstanders at a relative bargain price.

Many great suggestions here. I own the Harbeth 40.2 anniversary speakers so a little biased but I want to give them a shout-out. I think you can find them for a little less than 10K and while technically a bookshelf speaker, I'd say they'd be fine for your application.

To fill the large room with ample bass and an engaging midrange voices:

+1 GoldenEar Triton Reference - very generous powered bass, fantastic soundstage, engaging musical sound. Would also work well in home theater

+1 Klipsch Khorn or La Scala - very high efficiency ideal for warm tube amplification which would give warm midrange - magical with voices. Very horn quick and effortless, but soundstage not a priority 

+1 Pure Audio Project

Other floorstanders might also work in the large space, but will need strong bass drivers since no subwoofers.

@bigasscab honestly I have never seen a more hodgepodge collection of answers.  I think you are better off ignoring most every answer here and just go listen to some.  A few are great speakers.  Even an audio show in small rooms will give you ideas about how speakers  / electronics fill a room.  I do agree two subs is the way to go, even with large cones and big cabinets.  They always improve things.   Don't skimp on the electronics.  But you do have to decide on type, as about 5 types have been recommended here:  360 degree emitters (ohm, mbl) electrostatic panels, horns,  sealed and ported designs.  I would stick with conventional designs, ports or not, and consider two subs.
