Late to the party here but can add this…
I recently built a pair of horn based, coaxial floor standers using Radian (pro) drivers. These (and similar) have been used to great success by Live Act Audio, Daniel Hertz, Coherent Audio, Spatial Audio and others, in various sizes, boxes, open baffle, on and on…you get the picture. With proper “Home Audio, audiophile” crossovers and proper enclosures, the Prototypes I made allowed me to break free from 40 years of Panel speakers. (I had Quad 63, Martin Logan ESL and Eminent Technology LFT 8 all at the same time until this past year and have sold them all on CAM). The experimental (first) pair I built are so good that I may not commit to the Ultimate Version I had planned. I now enjoy All the detail and imaging but with real Dynamic Range!
Try the Pro Audio stuff but take the above advice of others here and be aware of Pro Crossovers and enclosures, as they both are not suitable for home use.
Enjoy the experience of trying Something Completely Different
