Ok, well i bought a new QSC RMX1850 new in original box for 400 about 2wks ago and havent been able to use it because I didnt have the correct speakon cable and I was too lazy to order one online . Any how I finally found a store that had NL4fc Neutrick conector and made my own peakon to speakon cable using 12ga speaker wire. I tried the amp in a loud band practice session today in bridged mono mode and it kicked some serious a**!!!!!!! This thing was hella loud compared to my crest and I didn't even need to push it to clipping to get the loudness that I needed. I just wanted to say thanks to all the people that recommend QSC and I can safely say that after my experience with my small ampeg head and the low line crest it will always be QSC for me. Thanks for letting me rave a bit and to Bob Lee you guys make a sweet product!
