I have, as of now, 5 sound system in my home and all of them use Klipsch speakers.
I do like the sound of the G-17, but, don't try to listen some pop or dance music with a lot of bass on it. It will distort and you don't even have to listen at loud volumes to ear it.
Other than that the sound is very good, even if I liked the sound of the Zeppelin Air more. But, the Zeppelin was too big to be put where my G-17 is. Because of that, I consider the G-17 a good compromise.
