pricewise they are in the FBT maxx4A bracket and RCF 322 or 325A so I assme they score heavily on weight
I used to have a pair of the older Opera 602 and they sounded really nice, but once you start to push them a bit the sound does suffer terribly from signal compression due to running out of headroom. They're not in the same league as the RCF Art series, no way. Sound quality is quite a bit better on the RCF and I can say that from experience of hearing the Art series. I very much doubt the newer 605D you're talking about will be a massive improvement over the 602 I used to have, but for the money they are very nice speakers. Just set gain structure properly first and then dont run past the 0db light on the dj mixer and you'll have good sound quality.
