Concluding my DSP journey. The first attachment shows the room response with the DSP set for a gain of -5dB and a Q=3 (green is L+R, red is R, and blue is L). As shown previously, these settings will correct the perceived Left-Right imbalance, but the right channel is now pulled down enough to...

Just a follow up on my DSP room correction adventure. I investigated using the REW software to generate the EQ filter, but I found only settings for increasing bass response, and no way to affect a decrease, so I gave up on that approach. I decided to just try decreasing the right channel by...

kemmier3D, thanks for your comments. I am in the process of reading-up on the REW approach, but will take your advice on knocking-down the 40 Hz peak. Cheers, Darra

I decided to go the DSP route. I purchased a MiniDSP Flex/Digital. As I see it, I have three options for dealing with the channel imbalance: 1 – pull up the left channel by +5dB between 70 and 200 Hz. 2 – reduce the right channel by -5dB between 70 and 200 Hz. 3 – pull up the left channel by...

suttondesign, thanks for that suggestion, I will look into it. Ogoript, OK, now I understand what you are suggesting. From the impulse response data for these room curves, I have from 5 to 12 reflections in the first 20ms for both channels. I will delve into that data a bit more to see if the...

suttondesign, thanks for your comment, I have thought that signal processing might be the way to go. Of course, the next thought is analog or digital? Any advice on that subject? ogoript, thanks for your comment. By using the mirror technique, I have found the first reflection points for both...

Hello All and Happy New Year, The first attachment shows a diagram of my listening room. I know, other more traditional speaker and listener locations would be better, but this is also a family living room, and this just works best for us. The speakers are Magnepan 3.7i’s, with tweeters on the...

My listening room (8' ceilings) to add to your collection. Cheers
