Most speakers are designed with the emphasis on good on-axis response, with the expectation that they will be listened to from close enough that the first-arrival sound will dominate over the reverberant energy as far as tonal balance goes.
But in a very large room, assuming you listen from fairly far away, the reverberant energy will dominate the tonal balance. In that sort of situation, the speaker's power response (summed omnidirectional response) will matter more than its on-axis response. Far more.
My first sobering encounter with the importance of power response in a large room came back in the late 80's, when I took my killer homebrew speakers to a small-scale dance that was held in a back room at a church (about twice the size of your future room). I was very excited about showing off my talent. The speakers had a 15" woofer, 7" midrange and 1" dome tweeter. Well, they sounded like crap in that room! I was truly horrified, and had no explanation (the concepts in the first two paragraphs above were unknown to me at that time).
The answer would have been speakers with good radiation pattern control. That's one of the reasons prosound speakers are configured the way they are (big woofers, big horns) - not only does that give high output, but it gives decent radiation pattern control, and that's what works in a big space.
The Sunny Cable speakers you mention are like high-end variations on a prosound-ish theme. They almost certainly have a much smoother power response than conventional direct-radiator speakers, mainly because horns do a good job of radiation pattern control - which relates directly to the power response - which relates directly to the tonal balance in a very large room.
There are other ways to get good power response, but a high quality horn-type system is among the front-runners for a very large room in my opinion.
