Total bass suck out at 40hz


So I'm a little slow, but it occured to me today to see if there were test tones recordings on Tidal of Qobuz. Yes there are. I have a radio shack SPL meter so I went to work playing them to see what I had in my room. I was shocked to find a total lack of audible bass at 40hz. At first I thought they must have made an error in the recording. Then I went to a different set of test tones and wow same thing. I never dreamed something like that would take place. I have read a lot of discussions about bass peaks and nulls and always thought it would just be slightly less in volume at the null, not completely gone. So Am I imagining this and if not what do I do to remedy it. I am apparently missing a lot of music and never knew it. I am currently listening to my freshly refinished Yamaha NS 1000m speakers(just put them in the system Wednesday after work) with a Modwright KWI 200 integrated amp and a Lumin streamer/dac. I also have stereo Rythmik  F12 subs. Thanks, Allen.

who would have thought that it would be so absolutely awesome. I don't know why it works but it dang sure does.
Actually the explanation for why is posted above. And also explains why the 4th will help too- but beyond that is a vastly diminishing return. Glad you're getting it sorted out!
Yes sir, I actually know why it works, I was being a wee bit facetious, thanks for you thoughts.(Giddy with delight)
try putting the subs on the wall behind your listening position and have them fire looking towards the fronts. Reverse the polarty on them and you will get a smoother response than you now are getting.
