There's also another upload (also with 30 Hz rumble) but the one above seem to be more similar to your spectrum:

Damn this is hard on the subBe careful with this
Good onePerhaps The Chain by Fleetwood mac?
Bass from the ~3 minute mark plays at 41Hz which is the lowest a normally tuned bass guitar plays (E string played open).
This is a real torture track..Here is what distorted with me
This is a real torture track..Here is what distorted with me
Svs sb 1000 pro at max volume showed me that one of my subs is damaged
Audio technica m50x
truthear zero red
what did not distort is the cheapest
7hz zero 2
Turns out one sub is defective and for 2 months did not hear it with my music and volume. It rattles between 20 and 27hz. I can get it to rattle at full volume and tone generator.Did you turn your sub all the way up and cause damage?
And you didn't hear distortion at 7Hz on one of the subs? It may have a limiter or something that prevents it from playing that low.
Anotherthing when i put tone generator at full volume for a few minutes a plastic burning smell comes out.
