>I'm an EDM guy and demand a certain performance to 20hz, which homepod lacks.

I've checked a lot of dance music and never found anything with meaningful 20Hz content. It's extremely rare for "deep bass" to be lower than 40Hz. The only genre I can think of that often has very deep bass is pipe organ music.

EDIT: Movie soundtracks also commonly have <40Hz content for sound effects.

This. Even with a giant subwoofer system, 20 hz is more felt than heard. The "deep 808 bass drum" usually centered between 40-60 hz. My Tr-808 was centered at ~53 hz. Keep in mind that a doubling of frequency is an octave, so 26.5 hz would be an octave down and 106hz would be an octave higher

I always understood ~20Hz to be relegated more for inaudible movie effects like you mentioned. Usually contributing to the feeling of dread, fear, and anxiety in horror movies, etc.

It’s news to me that one might need 20Hz for purely an audio track, especially in the home. I would understand at a concert or something but to demand it from a single small self-contained unit like that sounds like looking for love in all the wrong places.

Ah yes, the subwoofer rattling sound. Dreadful indeed. Can kinda take me out of it.

I wonder if the "undertone series" for a bass hits this, since a low E on a 4-string already is at the ~40hz range. Definitely something that's felt, more than heard, as you mention.

Pipe organ music can commonly reach down to 16 hz or so, but for those looking for (slightly) more current music containing truly deep bass here are a few options:

Pink Floyd- Dark Side of the moon. The Heartbeat in the introduction contains significant energy in the 20-40hz range

Bass Mekanik- Each of his releases includes some music but also features a test section which will play frequencies with labels as to their frequency. Even if this sort of music isnt your thing it is helpful if you are curious as to what the frequency response of your stereo.

Tchaikovsky 1812 overture- Cannon Blasts go sub sonic.

Of similar vintage to Bass Mekanik, The Crystal Method's "High Roller" has some very deep, musical bass in the first minute. This bass is lost entirely by most MP3 encodings. Makes for a good reference point for both subwoofers and music sources!

Agreed. Also a really clean recording, though somewhat over squashed dynamics. But love those drums...
