RE: Room correction systems W/ Maggies

Yes room correction works for panels. Everyone has some room issues. Frequency response problems can be compounded by bi/tri-amping a system. Without some way to measure both you really have no idea. Of course whether it bothers you or not is another matter - ignorance can be bliss.

I have played around for two years with a Dspeaker Anti-mode 2.0 Dual Core digital correction device and have learned a lot on my tri-amped (w/sub) modified Maggie 3.6+ sub system. Generally: 1) Digital room correction is best suited for frequencies below 500Hz to deal with room modes. You can use room treatment and speaker placement to solve for everything else; 2) Narrow-band room mode dips are not audible which is good because they are not really correctible with DSP; 2)Peaks are treatable with DSP. You may or may not hear the difference after correction depending on how broad and "peaky" your frequency response problem is. I've adjusted narrow peaks of 3dB or so below 80Hz and honestly couldn't hear the difference on the before and after (my system is flat to 20Hz).; 3)Depending on the transparency of your system you may not want to add other signal processing.

So for me, I didn't end up using the Dspeaker gizmo in my system for room correction. I have used it for speaker placement, setting crossover frequencies and room treatment. There are other better tools to measure with, REW etc. At one point after hundreds of hours of adjustments, my room response looked something like this in this old pic (pretty flat considering minimal octave smoothing here). It's better now as I'm still measuring and adjusting but it sounds really good to me and I'd rather not have more stuff in the signal path.

Love those frequency sweep tones!
