    Re: port length question

    ok so correct me if im wrong please. Using a 2.25" vent, if i went 8.5" deep and made the L shape and went 14.75" i would end up at around 30 HZ?

    Re: port length question

    anybody? im getting a 15 se and want to tune it around 30Hz using the external dimensions of 37.5" wide x 16" high and 12.25" deep. im looking at all these calculators but their all giving me different answers and its just confusing me even more.

    Re: port length question

    With those external dimensions, and a port that is 2.25" wide x 14.5" tall (box height) you're only going to get ~2.1 cubes after all displacements if you tune to 30Hz.

    Re: port length question

    I'm not overly familiar with the SE's, but RE reccomends 4 cubes ported for SQL, and I probably wouldn't go lower than 3 cubes.

    It won't necessarily hurt the driver, but I think you'd yield better results just going sealed. You'll be able to give it the proper volume it needs (~2 cubes), and it should sound great.

    Re: port length question

    Put it this way. Tuning a ported box low is done in an attempt to get teh frequency response of a sealed enclosure. You lose a little output going sealed, but the low end is better.

    In your case though, I don't think you'd lose much output at all because you're starving the SE if you throw it in 2 cubes ported.

    Re: port length question

    so in my situation it would be better overall to just go sealed.

    Re: port length question

    i would say go sealed.

    remember the lower you tune the longer your port lenght will become.
