In this video, I talk about the LFE+Mains setting on your receiver or pre/pro (sometimes called "Double Bass" in other receivers), what it does and issues you can run into by enabling it. I also go over measurements using REW that I've done on my system, both before enabling LFE+Mains, after, and some things I tried to help get a better response after it was enabled.
