I've built a pair of speakers for in my kitchen. The kit I've built is the "Samuel HQ" by Heissmann Acoustics (original kit measurements are on this page): https://heissmann-acoustics.de/en/samuel-hq-sph175hq-xt300-xt25/ My kitchen is 5.5x5 meters, and sadly I have no choice in speaker positioning - they're completely in the corners, nothing I can do about that. My usual listening position means they're at approximately 45 degrees instead of 30, and the right speaker can't be completely toed in to point at me. As can be expected this results in less than optimal sound. Maybe an important note: I am not looking for audiophile perfection. I just want to make an agreeable best of a bad situation, averaged for a wide listening position (give or take a meter :-)). A friend borrowed me his Umik1 for as long as I like, so I started to read up on room correction and REW. I've read quite a few tutorials on different forums and I think I have a fairly decent understanding now - for a beginner ;-) I've tried a few different approaches so far - one sweep measurement at the listening position, 9 sweep measurements on/around the listening position, and averaged RTA measurements left and right of my head at the listening position. I'm doing my measurements and tests using a laptop and Equalizer APO, but in the end I am using a Raspberry Pi with a Hifiberry DAC+ DSP for the permanent eq setup. My questions: I read on multiple occasions that REW EQ correction is best used on the low end - say below 400hz. But my measurements show a significant boost in the high end that I would like to tame. (I'd prefer to end up with something like Olive/Toole house curve) I've been able to do that perfectly fine using target matching to 20khz, but as mentioned a lot of people say it's bad to do correction above the bass frequencies. Am I going the wrong way applying EQ all the way up and if so - why, and how could I get my sound okay without doing that then? Next, I have some dips in bass response. I can fix them by boosting, but generally I read that boosting is ill-advised because it puts more strain on the amplifier. Okay, but , I *do* want to get the correct response! :-) Another thing - I read that having lots of filters is a bad thing, indicative of a wrong approach. Yet if I tell REW I want to get close to 1dB matching I get a really nice prediction - but lots of filters. I realize this is all much more complex than my understanding of it as of now. Can you give me more understanding on how to go about all of this? Edit: Here's the graph of my listening-position measurement using RTA of the right speaker (which is positioned most problematic), using var smoothing. I'd think the 46 hz dip would be a room mode response, but this was an RTA measurement of a 30x30x30cm area to the right of my head - shouldn't the area averaging take care of room modes? What would be your approach to correct this speaker's response?
