I've owned the RTi6s for about a year. Yesterday I finally got around to buying speaker stands, and the salesman at the music store (musical instruments, not CDs) referred to the RTis as "home theatre speakers". I said, "they handle music pretty well too."
Is the fact that many people consider them "bright" the reason why music is not considered their strength? I'm certainly not a true audiophile, but I enjoy listening to music on my RTis.
