desltz,
Your large room and high ceiling might make bass reproduction difficult for some speakers. My bet would be on the Rivals, among the three choices, working the best in that situation. But, these days, many single driver or small driver two-way systems are quite capable to performing well in large spaces.
I heard a system that employed a single 8" fullrange driver, but, it was supplemented with active woofers coming in to handle deep bass. It was shown at an audio show in a fairly large ballroom. I was surprised at how good it sounded and how well it filled the space and played at very high volume level. The speaker was the Cube Audio Nenuphar Basis speaker.
I also heard two-way Acora speakers demonstrated in a large ballroom also do a good job filling the space and providing adequate bass.
If one can place the speaker near a corner, Audio Note AN-E speakers, which utilize an 8" woofer and a dome tweeter sound terrific and can fill large spaces and deliver fairly high volume.
