[Do sealed boxes have a tuning frequency?]

ok i have a qusetion. so if my subsonic filter is off and i have a ported box let say tuned to 33 hz my sub is at risk? when my head unit is at negtive 7 for subwoofer preout and bass at 0 and treble for speakers at 8 and mid at 8 for the car speakers?

Yeo, subwoofers do what's called "unloading" below tuning frequency, the cone isn't moving properly, the sub will be moving much more than it should be and you are risking mechanical and thermal failure.

ok thank you. what if i was using a sealed box would it be a problem there as much for a ported box?
