Wow, for the money if they sound decent that's a deal. I've been so in love with JBL's over the years I'm always worried if anything else has that full, smooth JBL sound. But, I also know technology marches on and I've heard some no name (to me) brands that sounded pretty good. Kustom speakers used to be pure crap, so were the old Peavey's, those early Fender PA's, and others but lately I've heard people using new versions of all of those and either my ears are going or they sound really good.
I wouldn't use that RA100, it's just too weak. I use one for my home studio. Just playing my keyboard at a comfortable volume in my bedroom requires that amp be set at about 5 for both channels with the channel strips on my mixer up full. You can find a RA300 for around $150 on Ebay, much better for live work.
