i have diamond S600S components and I like have never been happier with my purchase. paid like 215 shipped on ebay and they are unbelievable. i think theyre rated at like 150 and i was givin em like 175 for a while and they took it like champs. the crossovers feel like bricks and are so quality. I have mine on a 300/2 and the sq is great. id say get the silks though, less strain on your ears in the long run. all in all, buy em, you WILL NOT regret it.
