Which speakers will fill 5,000 cubic ft coherently

Sure you could change to bigger louder speakers, but, if I were you I'd experiment with subwoofers to provide the sound you want. Your speakers are fabulous,very hard to beat at what they do, but were designed to be used with subs. Experiment with quality fast subs.<<

I believe these speakers were designed for smaller spaces, and have already sold them. Besides, I dont believe that the vertical soundstage and imaging would be that much affected by subs. But it's moot.

Hard to believe, but adding a sub (or two) to monitors has a substantial effect on increased image height and size. Quite amazing, actually...<<

Should I cancel the sale?:):) 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........

Your request for education is refreshing. Help is on the way.
What Tvad says about subwoofer implementation, however strange, is certainly true. Incorporating subs can be very tricky,as you need to place them in such a way as to blend with the speakers you have already. Purchasing speakers with pre-engineered and pre-optimized inboard subs removes obstacles that you otherwise might never overcome. It is also advantageous to consider powered speakers which have onboard amplification and generally exclude passive crossovers and the compromises they introduce. The better powered speakers often have a separate amp for every driver and an electronic (active) crossover on hand to handle crossover points and slope assignments.
It is also advantageous to reproduce as wide a midband as possible without crossing over at all. This is usually the province of very small limited range dynamic drivers like Lowther and Fostex or rather large planars like Sound Lab or Magnepan. The former will not begin to fill your spave and the latter is too large for where you need to put them.
While we are at it, Beveridge is not only too large to fit but needs surrounding space which you certainly can't provide. Another suggestion called for Infinity Kappa Nines. These, if I remember correctly, hold a special place in the H.O.F. for hardest to drive speakers of all time. A very, very unwise choice for an OTL owner.

I'm a Zu guy as is well known but there are some other speakers that might suit your purposes. Perhaps Vandy Fives would fit.
