Yep. They are a bit underrated. Expect between 530-580W max on the birthsheet. Should give about 2x175w rms @ 4 Ohms, maybe a little more. The 720PRS need only about 110-160w rms to really come alive from what I've read.
[edit]
forgot to mention I auditioned them on a Pioneer D2100 ICE amp (2x150w rms) and they sounded spectacular. HU was the 880PRS.
