Subsonic Filter on a sealed enclosure

[DanP 19]

Im building a sealed enclosure for my 2 15" Obsidians that's gonna be about 4 Cu Ft. after displacement. I plan on using my Hifonics Zeus 2000 which has a subsonic filter on it which for my ported enclosure I set about 5 Hz under my Box tuning. There's no option to turn the Subsonic filter off so I'm wondering what exactly I should set it at when using it for a sealed enclosure.

 

Sorry if this lacks detail I'm unsure how/what to base setting it off of so I'm not sure what else to include.

No need for a subsonic filter with a sealed box. I can't remember why but sealed boxes don't use one.

Yeah I imagined that but since my subsonic filter doesn't have an option to turn it off, would I just turn it to the lowest setting?

Yea just turn it all the way down.

the human ear (depending on the person) can only hear down to 20-5ish hertz.  music rarely plays below 28-30.  it really doesnt matter tho, turn that puppy all the way down and volume knob all the way up!
