Just bought these for my digital piano setup, where I often use my laptop and DAW as well to control virtual instruments, piano or otherwise. An unideal acoustic space in the corner of a railroad-style apartment.
So far quite impressed, if not surprised given the measurements. At just 2 feet away from my ears, I feel more than fine with the dynamic capability. The original Micros we're already fine for me, they just tended to have a bit of port noise and maybe sounded a little messy. These are much more capable in SPL by comparison.
I seem to have lucked out with the built-in calibration too -- it was an immediately obvious improvement and didn't seem to do much damage above the bass. It's not perfect, as there are still a few somewhat boomy notes, but it's no contest between the uncalibrated sound and the calibrated one.
Unfortunately I mistakenly thought that id be able to load the more advanced Arc 3 calibration directly onto the speakers. I don't have my laptop to the piano half the time, so at this point I am still wondering whether I'd be better off just getting a minidsp to make my own calibration with REW. Part of the reason I bought these was that I thought I could save some money on a DSP unit. There's also a stray source of noise somewhere along my signal chain but it doesn't seem to have anything to do with the speakers themselves.
Still, I wouldn't hesitate to recommend these for very nearfield setups. I hope iLoud considers some more flexibility with the calibration going forward. Being able to limit the calibration range or load your own custom calibration onto the speakers would be great upgrades for us tinkerers.
