Hello there. Been browsing the site a lot lately This is my first post, to see if I might get any feedback on a question I have about some REW measurements and EQ adjustments I made.
My question is about the effects of EQ filters generated by REW after performing MMM measurements. A couple of bass peaks were improved, but there's a new dip in the bass that seems to have been caused by the filters. Should I lower the values of the EQ filters around that dip, or add another filter to bring it up and compensate for it, or...? Any suggestions or input would be greatly appreciated! I am just starting to learn about acoustics, etc., so I'm just trying to get a better sense of what's going on with my speakers and in my room and how these measurements and adjustments are affecting things.
I have read the REW Help thread and the MMM for dummies thread. I used the MMM method for this measurement using a Umik-1. I've made several measurements over the past few days and they've been quite consistent, so I don't think I'm doing anything wrong with the measurement.
The speakers are a pair of KEF LSX II. No subwoofer. The listening/measuring position and speakers are set up in an equilateral triangle. The speakers are at the front edge of a low table, about 25cm from the wall behind them. Here is a quick sketch of the room and setup:
Measuring using the MMM method, I got these results:
REW created these filters:
Then I used the "Measure with these filters" button in the EQ settings, which yielded this result:
The peaks in the bass seem to be improved! But there's quite a big dip around 60Hz that wasn't there before. Any thoughts or suggestions would be greatly appreciated!
