KRK ERGO

I just returned mine. I tried it on a whim -- easy to find from the big name online music stores w/return policy. I was excited at the notion of room correction utilizing the famous Lyngdorf Room perfect technology for $500, and hoping for distinct improvement in my rather bright and slap-happy room. But for whatever reason it boosted the mid-bass and bass WAY up. There was no way the room was 'corrected'. In fact, it was intolerable. It apparently thought my room acoustics weren't muddy enough. I tried multiple times with different mic positions, etc -- same result every time. And then the software stopped working properly. I gave up.

I read another post in another forum where someone had a similar problem. I'm guessing it's an anomoly since there have been many successful reports. Ah well, back to good ol fashioned wall panels

I haven't measured my room -- that would be the hard way. I was hoping the KRK would just do its thing. The room suffers primarily from a lot of reflective surfaces and open area creating slap echo. Addtionally I have vaulted ceilings that go to 12'. I've treated upper corners, rear wall (since my head is close to it), behind speakers. First reflection points, ceiling are likely next. I'm addressing the issue more seriously now that I'll be doing the work.

The Ergo asks for multiple mic placements after the focus position. It did not ask for specific mic placements -- in fact it specified to get very general with mic placements to emulate real world listening from a global standpoint. Different positions until it measures 90% understanding or above -- plug and play. But I can't believe that the room corrections it did were trying to compensate for any brightness. They were flat out BLOATED. My room is not atypical -- it's a living room, with the usual plants, couch, curtains, rugs, etc. There is some slap echo, but nothing out of the ordinary.

If you're also citing level mismatch between channels -- are you referring to db levels at the listening position? Not the case with me. My levels were matched.

As I said, perhaps my experience was an anomaly, though one I wasn't expecting. I'm saddened with the results and don't know what to attribute them to. No doubt that others have had better experiences, but mine have not been.

my level matching comment was directed at Bob_reynolds. Regardless, it's puzzling why it measured the way it did. No idea. I did contact them (never got a reply) but when the software glitched out after hitting Cancel during a test (subsequent test initiations never got past the 'clearing the old information' phase) that was it for me. Didn't work, software glitchy, give me a refund.

You can easily hit the focus/wide button to turn it off and on

Perhaps that could mean that your room is already well treated and/or acoustically correct?
