I have a used QSC RMX 2450 for sale. It is in great shape. In the picture it looks like there are marks on the front but it is just a little dust. I don't have the original box but I will pack it well. I bought it used about a year ago and didn't end up using it more than a few times. The previous owner used it in a home karaoke setup. I would like to get $375 obo.
