I own a pair. They have astonishing clarity. You seem to know that they don't play loud, but people have different ideas of what is loud for them - I'll leave you to judge.
My room is 20x14x8 with a large coupled room which makes it about the size of yours. I was quite happy with how loud the 989's played.
For the bottom octave, you should look at a sub. Without wishing to stir up a hornets nest, you should consider doing bass management and steer low frequencies away from the quads. This is best done digitally.
As for placement, they need space, but they are not nearly as fussy as some folks like to make out.
I'd suggest you consider some more powerful (solid-state) amplification too - I used Bryston PowerPaks.
I've tried all kinds of music. Good speakers are good speakers and the notion that some speakers are good for only some kinds of music is nonsense. Rock music sounds fantastic on quads, you'll only be limited to how loud you can play..
They do "beam" and have a sweet spot. This might be an issue if you are trying to fill a room for other listeners. They are not a "party" speaker.
Finally, these are big speakers, which dominate a room. Make sure that they are acceptable to your family. Home demo is advisable if you can swing it with your dealer.
