Box I’m about to build for low lows tuned 21hz 1 15

[camshairtricks]

i think if i went port up id have a lot of roof flex i think thats why it dont flex . the only way i can make my roof flex a little is if i play like 36hz an up . threre is no flex that you can see on camera when i play real low notes

Not sure if that makes this situation better or worse. ?

Cam, your just being ignorant.

You have some grandiose delusions on your box, tuning, and port size.

You can't hear 21hz, that is just nothing more than a glorified air pump for hairtricks.

You have been given great advice that you simply ignore, and substitute it with your own.

Alt is 130a at 13.5. Not bad for stock.

Mine says 150 amp on the case have no clue why one is that big . And skulls are you kidding ? Can’t hear 21 hz what planet do you come from ? Bec the human ear can hear down to 20hz if it’s loud enough

I have no prob hearing 20hz . Now 19hz is a little different it’s harder to hear

Whats the cutoff slope for the high pass filter for the human ear. That must be like 100dB/oct to hear 20 but not 19

You guys do realize that I am running 50sq inches of port area right now that’s plenty for the sub I have I have the sub what they told me to give it but everything else I did with my box is not recommended for this sub
