Their biggest problem is their size. They require a rather large room to sound their best. Not to mention high power amplification. And even though I've not heard them, I quite imagine they are magnificent sounding.
That said, if I were buying speakers at their price point - basically cost-no-object - I would give priority to big Soundlabs.

Follow Ups:
A guy who used to post here was a proponent of Sanders electrostatic speakers over other similar types. They are "hybrid" speakers (similar to Martin Logan) with transmission line subwoofers. They also feature digital active crossovers, room correction, etc.., in an integrated system. Sanders are narrow dispersion/flat panel speakers with a narrow listening window. And because they are relatively slim narrow dispersion speakers, a very large room is not always needed. You get a lot for your money with Sanders, no doubt about it...Soundlabs speakers are wide dispersion/wide listening window AFAIK. Wide dispersion speakers normally create "comb-filtering" problems, but the curved panels of Soundlabs speakers helps to spread sound out while minimize comb-filtering problems. This type of speaker is most expensive to build, hence the high prices.
I would suggest that anyone with enough bucks to buy and use large panel speakers should try to audition different types and brands before buying.
The Magnepan 1.6 speakers I used to own produced the illusion of a big soundstage but were in fact more "directional" than I would have liked. They had a definite "sweet spot" for listening, or so I had thought. I would assume that the 30.7s are basically the same way, but I really don't know because I've never heard them.

driven primarily by Asian markets but applicable to anyone is a series of narrower SL models using fewer "cells". Since they are inherently modular in construction, virtually any configuration is possible.
While the primary variable is height, previous models were usually seven flat cells across. Now there are three, four and five cell models to accommodate smaller rooms. Height usually isn't a challenge which is why I run narrow vintage Acoustat 1+1s in the home theater.
A number of variations are found here from largest to smallest full range models including the addition of thicker diaphragm subwoofer. The new models continue to support the three frame options of basic wood, furniture grade wood and rigid tubular steel. The "Build" link takes you through the selection process.

Dispersion per se really isn't the driving cause. Rather, it is typically found where multiple drivers (especially when widely spaced) cover the same frequency range where there is overlap with an apparent delay in radiation of a given frequency. Stacking conventional speakers (like Double Advents) is a common cause where the tweeters end up far apart. Even tightly spaced ones can potentially exhibit comb effects.
By contrast, Sound Lab's single diaphragm full range approach obviates that challenge. And due to their controlled directivity, they are designed to be used in arrays to further increase lateral or vertical coverage. How about using ten 22 degree 9' tall models ? ;)
