Can't beat them for the money
I used to own a studio, open to the public, and had to close it down. I really missed my old studio monitors, but because of lack of space I was unable to hook them back up. I looked at several options, and since I wasn't in business anymore, I couldn't afford the price tag on the Mackie HR series speakers, (I wish I could)
I did some research, and came across The Mackie MR series, took a chance and ordered a set of MR8s. Under my conditions, (Small Room, with poor acoustics) I thought that lack of bass response would be the problem. When I hooked them up, I found just the opposite to be true. The bass response was excessive. I'm not blaming that on the speakers, I'm blaming that on the room conditions. What I found was as I increased the distance between the speakers and the wall behind them, they began to level off, and the excessive bass decreased. When I had reached the limitation that the room allowed, for distance from the rear wall, it was close, but still a little bass heavy.
I was visiting a friend of mine, that was running a studio, and noticed that he was using the Mackie HR8s, and had them setting on pads, of acoustic foam, isolators, made by Auralex. I ordered a set, and problem solved. The problem was not the speakers, it was the room conditions and the acoustics. Don't get me wrong, if you have the money to take advantage of the Mackie HR series, that's what I would suggest. However if you can't, the MR series is a great choice. If you have a big room, the HR series has a huge advantage. If you have a small room like I do, the MR series will fit the bill. I close monitor at about 85 DB.
