I had plans to "upgrade" from my KRK Rokit 5 G4 and save space om my desk at the same time so I ordered the Iloud MTM's. I a/b'd the monitors on a track I'm working on where I made subtile changes to the sound of the bassline with Waves vitamin and Denise XL vst's, mostly affecting the region between 50- 250hz. On the MTM's I could bearly hear the difference turning the vst's on and off - they sound quite muffled, but on the KRK's the difference was crystal clear. The MTM's will be going back. Too bad, they looked good.
What settings on the back have you selected? How do you have them setup on your desk? Have you setup them so the tweeter is at your ear level? Have you tried to do room calibration? All these things are rather important.
