Steve149 I want to thank you for this video. I found it on youtube while I was searching for an array system for DJing. I was originally very interested in the new JBL PRX One, but at the time nobody had one to demo. When I started to look for alternatives I ran into your video and added the RCF J8 to my potential list. On my last wedding road trip (5,000 miles 6 weddings and a COL) I found a GC that had The RCF J8, Evox 8, PRX One, 3 Bose array systems, the HK Audio Polar, 2 LD systems, and the Evolve 50. In a head to head against all of them (and a K12.2) the RCF J8 impressed me enough to order 2 of them. I am thrilled with the crystal clear loudness that these things put out! These are some very serious speakers for a wedding DJ and the portability is wonderful. I was a QSC man before these. The J8 destroyed the K12.2 in a head to head!
