The best designs now are balanced force You put a driver in opposite sides of sealed enclosure so that their vibrational forces cancel out.

Nest 12dB on average. If we look at a safe subsonic frequency both can handle decently like about 25Hz the ported sub is 8dB louder. A sealed sub wont have as much impact at the same frequency but will give you more below that point.

An open enclosure is the most efficient a fully sealed infinite baffle enclosure is the least efficient and a ported or bass-reflex speaker is between the two typically 3 dB more sensitive than an infinite baffle. The acoustic-suspension woofer is still considered better in terms of lower harmonic distortion and less boominess and so forth but the ported designs of today are nevertheless excellent. It seems to me though that a sealed unit has better quality and can get to the ultra low frequency.

Another advantage is they usually always sound the same wherever they are placed in the room unlike a rear ported cabinet that changes with its distance from the wall.

However the tuning frequency is a pretty hard cutoff so there is little usable output below tuning no matter how beefy the woofer is. Bass is louder and more boomy less accurate Larger box size More efficient doesnt require as much amp power.
