Difference between SPL and window flexing bass?

Is there any? To my knowledge, SPL is just really loud music running at like 50-60hz.

So when making a box, is SPL what you want in reality for window flexage?

when you tune low thats where you end up flexing, for me that's how it has worked out

When I am going for spl I play the tone my car is and my box is tuned to. When everything is just right I get some harmonics going and my car "buzzes". The air feels thick and the car and glass seems to pulse.

Flex I just put on music crank it up and my hatch bulges 4 inches.

That's what I thought.

Problem is, you need a HUGE port to get into the ~20hz range for real flexing.

I ran 32hz which is what my box is supposed to be tune to and it did that "buzzing" think. I just don't like that much though, too many rattles.

If you want window flexing tune low with big ports and FEED SUBS POWER!

i peak at 49hz in my car the higher the tone the more buzzing but once i start to get down into the 32-40hz range thats when shit starts to flex and twist. my car is walled and once the flexing starts on the low tones the seats usually start to jump forward, doors bulge out, winshield starts bouncing but in general i prefer the higher tuning

I dont think i would ever tune a box in the 20hz range though.... considering 99% of the music you listen to doesnt get lower than 29-30hz.

High SPL can make a lot of flex, but more flex doesn't necessarily mean more SPL. It tends to be easier to make a lot of flex with a low note and low SPL than it does it with a higher note and higher SPL.
