Going below 20hz?

[joshpoints 10+ year member]

Do subs ever play below 20hz when playing music? The cd player that I have is rated at 20 hz and up. Will I be missing anything sound wise? I've seen some subs rated down to 18 hz but I'm guessing this is in the labs and doesn't occur in the real playing environment.

I doubt the human ear will hear the difference. First off thats only a 2 hz difference and second off that area and lower is hardly audible.

music rarely has tones lower than 30Hz som rap might get into the mid 20's but thats not often

Like the previous guy said the hearing range of most people is ~20hz to 20khz or something like that. Most normal music doesn't have a 20 hz tone... in fact there is only one that i can think of and it's a bass CD. "Bass Ryder"... i forget which cd i got if off of. And If you are using a ported box your subs will begin to distort by the time you hit 20hz... If you don't have a SSF on. Sub Sonic Filter BTW

ya i think you feel 30 hz and below more than you hear it.

The majority of the time that you think you hear a 20hz tone you aren't... the majority of the time you are just hearing it's harmonics and port air.

I've got a set of mbquart 12's, SEALED, rated down to 18htz. I've played a bass mekanik cd on them and I can hear MAYBE 20htz. The cd plays every tone from 10-up. At 10 you cant hear anything, but everything moves and the seats in my truck rattle. Starting at about 17-18 I can sence/hear some sound.

SOME rap tracks have some low tones, around 20 as mentioned, I found a few that may hit the 18 mark, its hard to tell without a meter or something.

you can feel it, you just cant hear it
