How Low?

[Alpine CDA-9815]

Alright maybe I'm going out of my mind from working long days, but how low dose everyone's component woofers play down to? While playing some more test tones I've noticed that mine play down to 10Hz .

10hz...amazing...lowest i carried mine was 30hz lowest

[80INCHES]

well i played a testtone of 13hz and all i hear is the panels shaking in my door..i see the sub moving but no sound..

80
i want to play a brown note on my comps..where can i get a brown note signal...i heard if u play 9hz at 128db's u will have uncontrolable bowel movement, in others word.....u wont be able 2 control your shiit

Mythbuster's tested it and determined it was a myth.

I agree with Jmac. You probably aren't hearing the 10hz tone.......your probably hearing either an upper harmonic artifact of that frequency, or the mechanical noise of the speaker itself, something in your car vibrating, etc etc.

Anyways.....with test tones and no crossover, you can get your mids to produce any frequency you want. Here is a 6.5" with a 2hz signal: http://diymobileaudio.com/pics/proto.avi

Considering human hearing ranges from 18 Hz to 23 kHz AT BEST, I highly doubt you're actually hearing a 10 Hz tone ... You're probably hearing the mechanical noise from your speaker struggling to try to play a 10 Hz tone

No not saying I heard it at all. Just wondering if it is normal for them to play that low... and with the way the settings on everything is set I don't know why they are.

Where is your highpass set, and what is the slope?

That's my thing... I didn't tweak the comp crossovers. I've only had 2 sets of comps and on both I had someone else adjust them. I told them how I wanted it, but that don't mean anything.

You should say that video is NWS....just make me skeet skeet skeet

Well I checked the comp crossover and it's set to "flat". Then on the "bi-amp norm" on both the of them it's set on the two top pins.

There are notes that can cause that kind of thing though, it's well documented, but I don't remember the link. It was the original inspiration for sound based weapon designs.

If it's so well documented where's the documents n00b!
