Which speakers will fill 5,000 cubic ft coherently

Are you saying that a recording of content (eg a soprano, violin, piccolo, flute, oboe) well above 60 Hz - an arbitrary cut-off for a suubwoofer - when the subwoofer presumably will not be employed (or will it??) raises the soundstage? What if I tell you that 90% of what I listen to is in the aove 60 Hz range? Then what? I am not being facetious - educate me........

If you listen primarily to recordings with music well above 60Hz, then I don't know what box speakers will provide the image you seek.
Any speaker that reproduces frequencies below 60Hz seems to be overkill and unnecessary if you don't listen to music in these frequencies. What you listen to seems ideal for monitors. Perhaps you would be better served by looking for monitors that perform differently than your Kharmas.

It seems to me you need high SPLs with wide dispersion.

How about a pair of Zu Audio Tones or Druids? When I heard both at a Zu Audio Demo, I preferred the Tones.

Maybe some monitor aficionados will offer suggestions. I'm out of ideas.

How about Vandersteen 5A's? Builtin sub amp - easy speaker to drive and fills my room perfectly - 23x15x14 with open back.

Vandersteen 5As certainly have great reviews. How sensitive are they to placement? Close to front walls?

I have mine out about 6 feet BUT since they have an adjustable 11 band bass eq and level/Q controls you can adjust for that pretty easy - soundstaging and imaging is better placed farther from the wall. They are rated at 87db but remember they have a 400wpc bass amp built in to each speaker. I drive mine with 70wpc Cary monos and they can play VERY loud if called on to do so ;)

Will they easily fill the room and does the soundstage extend vertically above the speakers (they are shorter than
the others I am considering)?
