At one point, I was debating between the Mackies and QSC. Then I found out how Mackie had switched production to factories outside the US, and shortly after that was when their reliability tanked in comparison to how they used to be. That added to the fact that QSC has (or at least had with the HPR series) a 6 year warranty… which is unheard of… I went with the QSC’s and couldn’t be happier. I picked up the KW181 last year, and can’t believe the power it has. I run it with two HPR 12’s, and it keeps up fine with them. JBL is pretty good too, but according to others, the QSC’s have better quality. I haven’t heard them, so I wouldn’t know, but I love my QSC’s.
