will not make a sound. i tried downloading the 1-35 hz sine sweep and nothing happens. even the 5 hz, 7 hz, 10 hz dont work. i thought it might be cause there so low that my comp speakers wont play em, so i put em on a cd and they wont play in my car. whats up with this? //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

your trying the hear 5hz?? Or am I missing something, I think Elephants can hear 5 hz

 

[jacko 10+ year member]

maybe because your box is tuned to 32hz? It's not going to play much of anything below 29-30hz.

 

[Ape 10+ year member]

and you cant hear below 20...

He should still be able to feel them though.., even if he can't hear it his subs would still have to be moving to be playing sound... //content.invisioncic.com/y282845/emoticons/veryhappy.gif.fec4fed33b4a1279cf10bdd45a039dae.gif If he's cd player/amps have a freq response of less than 20hz... some stop at 20hz, and he's subsonic filters are off... and I wouldn't expect the subs to play almost at all a few hz below the tuning freq.

Possible, but he did say

will not make a sound..

true... didn't catch that.

i understand that i wont be able to hear the subs, but like someone said i should be able to feel them. the subs wont even move when the songs are played.

i also tried playing the 35hz-1hz sine sweep. and it didnt make a sound at 35 hz. and i have played a 20hz tone in the past, so i know that its the files. what i am wanting to do is play a really low hz tone to watch the subs move...just for the heck of it. but i cant find one that will work.

how exactly are you burning them

 

[jujumantb 10+ year member]

Most CD players have in the specs like 15hz-25,000hz... if that means the internal amp will only play that range or the whole thing will only read that I dunno... //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

i used windows media player to burn them. it works fine everytime i use it.

i am using the factory hu in my mustang. not sure what the frequency range is.

I will give you the answer BUT only if you let me know the website you found your avatar pic at....//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

this is true. most equipment is AC coupled giving rise to a highpass filter effect at low frequencies. the theoretical ideal would be to make this be at 2hz to avoid any affects on phase or magnitude @ 20hz. but this is not reqired and most equipment is thusly speced to work from 20hz up.

this highpass filter is also useful to reduce DC offset, and many amps also add the effect in to the amp internally (usually on the feedback network).
