LOWS That'll make you shit on yourself!!!

eish.

true you won't hear it but you coudl feel  it. I can't hear frequencys below 26 hz( hear test)....... but i can feel those 20 hz so It woudl be cool to play 16 hz  and 36 hz and have them be at teh same volume. for SQL you need to beable to play HZ above 20,000 and below 20 hz because of the harmonics so it is resonable to have something that could play that low

Since we are on the subject of very low notes, I want to see someone try this test.... Sure you can tune a box to 16hz, but its hard to find a subs that can play at 16hz, with some serious authority, But what YOU CAN DO..... get 2 seperate boxes, same woofers, calculate some port/box designs, and tune each box 16hz apart.... Every frequency outside of that 16hz spectrum will cancel itself out because of the other frequencies involved. I think it will be better tuned about 10hz off, like 1 box tuned at 30hz, and 1 box at 40hz.... Why do this instead of 16hz? because its alot easier to get a higher spl at a higher frequency,

30hz + 40hz = 10hz peak spl freq....

sounds odd huh?

Oh yeah, 1 more thing... Iam a big Mythbusters fan, I LOVE THAT show. and the Brown Note, I really wish they had me do the testing, because those concert guys didnt know as much as they should have. Being surrounded by 24-36- 18" woofers playing a 7-9-11hz test tones, when the boxes are obviously tuned ALOT higher, like maybe 30-40hz, below that tunning freq, the speakers are only pushing out OUT OF PHASE USELESS AIR.... The sound waves were fighting eachother every way possible.

1) distance from the speaker was way off for 7hz tone, the effective sound wave length is about 40feet long, thats the 1/4 wave, not even the full wave length of 7hz to be effective.

2) Enclosed area, a warehouse would have been the best idea.... AND walled off from the envirnment, 40 feet long

Basically saying, The brown note would be best tested in the opening port end of a 7hz t-line subwoofer enclosure.... Which is insanely huge

I do believe the Brown note is possible, because I ALMOST experienced it one time, laying on a box with 2 15"s made out of a Ultra Light MDF, which was very flexible, vibrated my whole body, and got me very nasous (spelling) and made me want to vomit among other things

Sorry about being so long, just had to get that off my chest

I liked when they went to the sound off and filmed all the bad-ass systems. Sick az ^-^

Lots and lots of $$$$  $$$ spent but well worth it....

It showed Tommy a couple times, aka Ho Problems. :^

That guy wants to tune his box to 16hz and wants to know if 35-36hz  :owill pound if his box is tuned to 16. He doesn't want to pound at 16hz.

[Forevrbumpn]

I need glasses

But if he wants to tune at 16hz, and pound at 35hz, just use a 35hz bass boost, and he can tune it as low as he wants, wont kill anything, becuase the box will still be playing 35hz more, just cuz of the boost. But when there is a bass line below hearing, that car will vibrate like a mad man.

and yeah, should still pound at 35hz, even tho tuned at 16hz, but on a Impedance graph, and a mic test, the graphs would look odd

[going deaf]

16hz box will be useless for music and pretty much everything... you'll get no output at frequencies that high above your tuning. only thing it'll be good for is explosions in movies where it'll make stuff vibrate...

[Forevrbumpn]

one of my home audio sub configs I use a 20hz 3db bass boost, and a 10" with a 10" super high excursion passive radiator that has a Fs of 17hz 

explosions sound awesome when I hook that one up

but for now just the 40hz bandpass which shakes the house even more, and has like 3 times the output
