GNX104 any good?

kikiking

I am thinking about buying a pair of Polk GNX104. I have never used Polk before and wanted to see what you guys think. I will be setting them up parallel and connecting them to a Profile Clarus CL800 200W x 2 Amp. Will this sound good? Also I listen to metal and some rap and was wondering is these speakers will hit hard considering their low power range 50 - 175 watts.

Thanks:)
