I was able to compare 5200 directly against 7000 and agree with crion - they are on par with each other generally, but the 7000 produces much more intense bass;

that said, I was able to use dual subs (for a short while) coupled with the 5200, raised the 5200 crossover and achieve something very much like the 7000 sound for much less money....

Of course much of this depends on your room size and sound quality. i did this in a room small enough for the 5200 to easily fill. If your room is fairly large, the 7000 will really shine.
