It's not so much your room size I'd be concerned with but the 15' listening distance. If you play your music loud (as heard from your seating position) you're likely to strain speakers of that size and power handling.
Whether they're the best speakers under $5K is totally dependent on your personal preferences, not any pro review or marketing hype. I found them to be underwhelming and tonally inaccurate - somehow they managed to make plastic and fabric diaphragms sound like metal. That's how I hear them anyway.
I would look into a used pair of Devore O/93s or new Tannoy Eatons.
For fast and tight kickdrums, nothing I've heard at that price will beat Klipsch Cornwall IIIs. They can handle rock, classical and jazz with equal aplomb. Surprisingly, they're just as "warm" if not more so, than the Harbeths I've heard. They'll fill your space with rock concert SPLs if needed, but sound just as good at background levels.
