Interesting (almost) Subsonic Sound Test for your Headphones

Raise the very first slider (the brown one) on this one

Some of my headphones were able to output the very low frequency rumble (HD600), some did not produce any sound, or only harmonics when the volume is boosted exaggeratedly...
 
I found it to be an interesting/revealing (subjective) headphone test

Very funny and interesting. Listening to only the lowest frequency and I can feel my LCD-X's drivers are essentially vibrating.

more of a rumble on my LCD-2 than Ultrasone Sig Pros, but plenty of rumble on both...
weird feeling though...

Cool ambience. The brown slider says it's only 60 hz though.
