Hi, has anybody heard the B3031As, specifically in comparison with the jbl 308s? Sweetwater lists them as no longer available so they might have been discontinued, although they're still available on some other retail sites. I had a pair of b2021as that I was very happy with, but replaced them with some JBL 305s which I will be returning (guess I was hoping for a little more bass extension, but not really surprised about how they sound considering their size). I'll be using them for near/mid field listening. I'm also curious about the Mackie MR8mk3.
I would recommend doing some measurements with REW and either use the equalizer APO in Windows or a MiniDSP. It gives you so much better results than the controls on the back of the speakers.
I don't have a microphone for calibration... is miniDSP UMIK-1 the leading affordable candidate?
