In this video I upload a sinewave sweep from 30Hz down to .1Hz down to DC voltage. Test your sound system or equipment for its low frequency limitations.

Warning! These are very low frequencies including DC voltage that can damage sound systems. Proceed at low volumes with care. Most amplifiers will not reproduce DC voltage, but if you amp can, DC voltage can very quickly damage speakers.

30 seconds 30Hz to 1Hz
30 seconds 1Hz to .01Hz
10 Seconds DC +
10 Seconds DC -
18 Seconds 1Hz to 30Hz
30 Seconds 30Hz to 1Hz

How low does YouTube go?

For more fun analysis, check out the companion video where I downloaded this video from YouTube and loaded it back into Adobe Premiere and discuss and show the low frequency limit. Here is a link to that follow up video:
