RCF Active PA System (Art 712a & 905as)

Hey guys,

Just wondering if anyone has any experience with these?

What I'm I'm lugging around at the minute:
2x JBL MRX 525 15" dual full range speakers - 800w each
4x JBL MRX 518S 15" bass bins - 500w each
2x Crown XTi 2000w - 1 to power the tops and other for the bins.

I'm no expert but I'm just wondering if anyone can give me any advice on whether it would be a good idea to switch to the RCF system. It seems a lot more powerful for the size but would I be losing out on quality?

Play mainly hotels and large function rooms so would need that kind of power.

Thanks for any help guys, first time posting here!
