This is a full subwoofer calibration using my two subs from start to finish. It covers everything from time alignment to targets, volume, and sub-to-mains integration. Unfortunately, going over every aspect of the EQ made the video long. It's 3 hours, so I apologize for that. But I wanted to make a video talking about and going over every aspect of how I calibrate my subs, and the results are excellent! I made a few mistakes along the way. Because it's in video format, I had to think about so many parts, but I got to my goal in the end. I hope you enjoy it.
NOTE: Sorry for blocking the subwoofer volume measurement with my camera, I didn't realize that would be blocking it. I totally forgot. However, I do get to show the volume on the SPL screen, so you can eventually see the result. Again sorry.
UPDATE: Since calibrating this way, I've noticed that I didn't need to SPL balance at 2db hotter than the mains. So what I've done is level matched the subs to the mains instead, -2db lower. I noticed quite early that the subs sounded super hot, being 2db over. This fixed that, so if anyone has subs that are simply too loud, I would aim for your sub volume to be equal to your mains when using a Spear and Munsil UHD Benchmark 4K Disc. It makes sense to me now, that once you've got a great calibration in place, everything needs to be level matched perfectly, and there's no need to go over on volume for any channel once you get your calibration right.

Thank you for making great videos over the years. You've been a great inspiration to me in calibrating my system!
