Jim is probably in panic packing mode for Axpona, so I'll just offer a few comments. I've only compared the 3-way with my dome Song Towers. First off, almost no competently designed 2-way will sound like a competently designed 3-way (let's assume competence just for the heck of it). The dedicated midrange in a 3-way will almost always be smaller than the woofers in a 2 way, and will have superior dispersion. Plus, the woofers don't have to handle as much of the frequency spectrum, and that probably affect the midrange production favorably. As a result, the new 3-way has a fuller sound in the midrange than the ST's, and it throws a wider sound stage. The highs are probably very similar to the ribbon ST. As you mentioned, the bass extension is also deeper in the 3-way. That would normally mean significantly less sensitivity, since the ST's have two woofers working in parallel vs. only one woofer in the 3-way. However, the Satori woofer is larger (7.5" vs 5.5"), and the difference in sensitivity between the two speakers is pretty trivial. I might have more to say after I spend some dedicated listening time at Chicago and can compare the 3-ways with other offerings from competitors.
