More air in the cab = lower freq. peak?

I was wondering if you tuned low (32 and under.) Would you GENERALLY want more air in the cab to get higher scores? This is in general, i know you guys couldn't tell me what Db i was gonna hit blah blah blah. Before anyone say's it, I know each car is different and everything in the car affects numbers.

when you have more air space its usually easier to gain higher scores with multiple woofers, when you have more air, that doesnt mean youll gain a high school, some people get shocked for what it actually scores. Thats how it is in my jeep, moves decent air, but shitty to meter, have way to many air leaks in my jeep to compete.

Depends on a few things. Mostly dimensions. If you are talking about how loud on a meter, it would depend on how the wave lines up to the sensor and how it aligns with it's reflections.

a 32hz wave is 35ft long.
