I use it for 1 year as stage, the sound is good for this price range, and with a 31 band EQ and a measurement microphone they are really great.
I bought them for the test because there are not many reviews about this brand and I am very telling, even pro musicians with whom I worked did not find anything wrong with the sound on stage !!!
Eventually, I will have that MF 300 active or passive on stage !!!! For the front I'm JBL, but then it's not comparable, and that's not the same price !!!
