I have a whole slew of stuff in the forums for weak bass / harsh highs. The issue I found was that on LE - The calibration file is not true. The official response from Lonnie was that the calibration file and Dirac LE curve were adjusted to work together to come up with what they found to be a pleasing sound. Simple put, the measurements your seeing on Dirac with the emotiva mic are not accurate representation and your end result will not be the +3 to -3 as indicated by the dirac target curve. To correct this, I generated a calibration file from my cross spectrum microphones and this got things much closer. On top of that, Socketman sent his microphone to cross spectrum and shared his calibration. Both can be found in my signature along with instructions on how to apply them to Dirac LE. If you want to customize the curve further, I recommend the full version. (I still use my calibration files with the full version when using the EMM-1).
Tony, thanks so much for taking time to respond. You have provided some great information. I just downloaded your calibration files and when I have time I will take another go at Dirac LE using your recommendations.
Frankly, I have became so disenchanted with Dirac LE I just went back to my Preset 1 using manual measurements with a Rat Shack meter.
Based on your comments, I am even further disappointed that Dirac LE performs so badly. I really had high hopes this time. I stand by original statement that the single biggest problem area for home Hi-Fi and Home Theater is the Bass (100hz down to 20hz) region and that should be the primary focus to get right. I would have been much happier if Dirac LE was range limited to just the lower frequencies and nailed the results. Instead I've got what I consider incorrect bass adjustments that I simply can hear without a computer to tell me and questionable high frequency adjustments I can live without. I've got really good Speakers - Martin Logan Vantages that sound very good in my room without any EQ because I have taken care to locate. I've got them three feet from the wall and they have plenty of room to breath. Even before I ran Dirac, I knew I had some room gain at 50 hz that I again measured manually with the rat shack meter. I also have an adjustment control on my Martin Logans centered at 30 hz which helps tame bass modes. I can do all this manually and get good results. Right now Dirac LE is not working for me.
Everyone is saying how good the full Dirac is. That's great but I was sold on the idea that Dirac LE would get me in the ballpark. The money isn't really the issue, it's a drop in the bucket. It's the principle. I really think Emotiva should revisit this and take note of other people like me that are getting poor results. The way I see it Dirac LE should get you 80 to 90 percent the way there and Dirac Full should be the last bit of refinement. Right now Dirac LE is a disappointment and produces worst results than what I can do manually? What's the point of that? Why not add $100 to the price of the XMC-1 and include Full Dirac if that is the true solution. All that's been accomplished in my case is another example of how automated EQ systems do not work, which was my admittedly biased view before I began this exercise.
