Recommended Posts

Can someone please explain what the "Fs" rating means on a given sub. I see some with 34, 38, 31, etc...... Is lower the better?

fs is the frequency at which the sub naturally resonates.

4 15" dc audio level 4 xl's in 4th order blow through

2 IA 40.1's at 2 ohms strapped with 3.9 rise...currently own 4 IA 40.1s.....

1 06zx3504 running Kicker QS 6 1/2's

1 iraggi 180 amp alt

1 optima d34 yellow top under hood

5 deka intimidators

lower the number then means it would before better in a lowtuned box then and higher means it'll perform in a high tuned box i think i got it now,.

That's why they don't deliver.

Yer ass better go sit along the side of the road and wait.

You can't expect them to travel up some dirt road in a hick / back woods town. Thats how horror movies start :D

I explain things very simply and use analogies in terms of Pickles, and grape drink, pool noodles and jackhammers...if you can't put 2 and 2 together there man, There simply is not much more I can do.

Lower the Fs the better for daily, but Fs will drop when a sub is broken in. Typically a higher Fs of 42+ makes a good SPL sub.

Almost true, but a lot of other things come into play if a sub likes to go low or high.

Thinking is the root of all problems...

You ALWAYS get what you pay for.

well i see how a higher fs would be good for SPL since youd tune the box higher to get higher numbers.but i see now its all starting to come together.

That's why they don't deliver.
