Yes, nice. The LED meter on the 20-40Hz sub-sub band on my crossover lights a lot on both "videos."
But there's artificial "photoshopped" music and then there's natural music with lots side drum and other percussion: Copeland's Sym #3 (which is also a very nice symphony).
Here are some useful sound tests. Don't miss the Roland kick drum test... see if you can hear the difference between the last band (20) and next to last (30) and if the difference you hear is bass or is distortion arising from the presence of the 20 Hz signal in the clip:

Very interesting considering all the ambient noises traffic, TV, fans, etc. and sound system volume level, realize might be better to pick a quieter time to try this test. Also have to wonder about the sound systems ability to reproduce the test tones.
Could not hear a thing below 30hz with that makes me wonder about the search for a sub horn that can reach down to the 20hz area.

Of course a horn can play down to 20 Hz (and you need only one at those frequencies and not a giant amp either). But you have to tear down your house to make room for it.

Can hardly hear the 30Hz nothing below that unless premium sound system with powered subwoofer on the Support track. Again makes me question is it worth going after a horn sub that will reach down to 20Hz. When do we start to realize we have a 20 Hz signal if we cannot hear it.
Was thinking maybe much larger woofer to move more air will be doing more research.
Audiocheck.net, could hear the 20Hz with full volume. certain with larger woofer it would be more noticeable.

I believe people, maybe even those of us who spend a lot of time fussing with our woofers, are often misled about bass. For sure, the disco music crowd mistake bulging output at 50 Hz for serious low bass. I hope all readers know that your hearing system inserts in your mind the principle note when the overtones are played. And failing that, your loudspeakers will sure add their own harmonic-distortion "overtones" (which are easy to hear being higher) when they can't cleanly play the super-low note.
Being a fan of woofers, I've spent a lot of time looking at the bass content of my recording collection on a spectrum analyzer. Now, with my new crossover having a channel for 20-40 Hz content with its own level display, I having been spending some new and improved time on this question.
No question, jolly nice to have woofing down there... like St. Saen's 3rd Sym with the organ in it. (Be careful, some recordings have phony organ input.)
But also no question it is extremely rare to encounter. Maybe a few spots on my collection with any organ content below 32 Hz. Finally, systems that can't play that last octave are barely different sounding compared to those that can, even when those low notes are present, unless you all primed to sense the tiny shaking.

I think spectrograms are a great way to train your ear to recognize what you're hearing. Unless you do this and do frequency response tests to set up your system to reproduce as flat as possible then yeah, you're shooting into the darkness with what you think is going on. There is some pretty fun electronic music that puts content into the lower octaves and with a system like yours Ben, you might find yourself enjoying it even if the music isn't your cup of tea. I agree with you though, it is unfortunately rare to find something with good sounding bass down that low.
I'll have to open a thread with some suggestions and the spectrograms with them when I'm not so dag nab busy.
